OpenClaw Excel: Automate Spreadsheets from Your AI Agent

It’s the third Tuesday of the month. You know what that means: pulling last month’s sales data from the CRM, pasting it into Excel, applying formulas, formatting the table, generating pivot tables, and emailing the report to leadership by noon.

The whole thing takes ninety minutes. Eighty of those minutes are copy-paste and mouse clicks. Ten minutes is actual thinking.

Here’s what the same workflow looks like with OpenClaw Excel automation: you send one message to your AI agent. “Generate the monthly sales report for January and send it to the leadership channel.” Two minutes later, the formatted spreadsheet arrives in Slack with charts, conditional formatting, and a summary paragraph at the top.

That’s not a demo. That’s what teams are running in production right now with OpenClaw, the open-source AI agent framework with 145K+ GitHub stars. Your agent connects to Excel through skills, handles the data manipulation, and delivers the output wherever you need it. No macros to maintain. No VBA to debug. Just natural language instructions.

Why Automate Excel with OpenClaw?

Excel is the most flexible business tool ever built. It’s also the most time-consuming when you’re doing the same operations every week.

You’re already doing repetitive work. Monthly financial reports, weekly sales dashboards, inventory reconciliation, expense categorization — these are structured tasks. The inputs change, but the logic stays the same. That’s exactly what AI agents handle well.

Excel skills work where you work. OpenClaw agents connect to Telegram, WhatsApp, Discord, or Slack. You don’t need to open Excel, find the right workbook, run a macro, and export the file. You describe what you need, and your agent delivers the finished spreadsheet in the same chat window you’re already using for team communication.

It’s extensible. If the existing OpenClaw Excel skills don’t cover your specific workflow, write one. Skills are Markdown files with plain English instructions. Define your spreadsheet logic once, and your agent executes it every time you ask. For teams with custom reporting needs, this is faster than hiring a consultant to build a proprietary automation tool.

If you’re new to the OpenClaw ecosystem, our install guide covers agent setup from scratch. For the full range of business automation tools beyond Excel, check the Productivity category.

What Business Teams Use OpenClaw Excel For

Before we get into specific skills, here are the real-world use cases we’ve seen teams deploy with OpenClaw Excel automation.

Finance Teams: Monthly Close Reporting

Every month, finance teams pull data from multiple sources — accounting software, bank exports, payroll systems — and consolidate it into Excel for analysis. The spreadsheet structure rarely changes, but the data does.

With OpenClaw Excel skills, the process becomes: “Pull the January transactions and generate the monthly close report.” Your agent fetches the data, applies the standard formulas for variance analysis and budget tracking, formats the cells, and outputs a completed workbook. What used to take half a day now takes five minutes.

Sales Teams: Weekly Pipeline Reports

Sales managers need pipeline visibility. Who’s closing deals this week? What’s stuck in negotiation? Where’s the revenue forecast trending?

Most teams build these reports by exporting CRM data to Excel, calculating conversion rates, and emailing the spreadsheet around. OpenClaw Excel skills connect your agent to your CRM and Excel simultaneously. Ask for a pipeline update, and your agent builds the report with deal stages, probability-weighted forecasts, and trend charts. Send it directly to your Slack sales channel.

Operations Teams: Inventory Reconciliation

Warehouse teams track inventory in Excel. Stock arrives, orders ship out, and someone has to reconcile the spreadsheet with the physical count. Discrepancies get flagged for review.

An OpenClaw-powered workflow handles the reconciliation automatically. Feed your agent the current inventory file and the incoming shipment data. It cross-references quantities, highlights mismatches, and generates an exception report. The operations manager reviews the flagged items instead of manually checking every line.

HR Teams: Expense Tracking and Approval

Employees submit expense reports. Someone has to validate receipts, check policy compliance, categorize expenses, and approve reimbursements. It’s a lot of Excel work spread across multiple files.

With OpenClaw Excel automation, your agent processes expense submissions from email attachments, categorizes them by department and type, flags anything over policy limits, and consolidates approved expenses into a master spreadsheet for payroll. The HR team reviews exceptions instead of processing every receipt manually.

OpenClaw Excel Skills Worth Installing

The Productivity category includes several Excel-related skills. Here are the ones that consistently deliver results for business teams.

excel-automation

This is the core Excel skill for OpenClaw agents. It handles spreadsheet creation, data manipulation, formula application, formatting, and export to multiple file formats.

What it does:

• Creates new workbooks from scratch or templates
• Reads and writes data to specific cells or ranges
• Applies formulas (SUM, VLOOKUP, PIVOT, conditional logic)
• Formats cells (colors, borders, number formats, conditional formatting)
• Generates charts and pivot tables
• Exports to XLSX, CSV, or PDF

The skill works with both local Excel files and cloud-based spreadsheets (Google Sheets, Office 365). If your team uses Excel Online, your agent can update shared workbooks without downloading them locally.

Example use: “Create a sales report for Q4 2025 with revenue by region, apply conditional formatting to highlight top performers, and export as PDF.”

Install:

clawhub install excel-automation

csv-processor

Most business data starts as CSV exports from other systems. This skill handles CSV parsing, transformation, and conversion to Excel format.

What it does:

• Parses CSV files with custom delimiters and encodings
• Filters rows based on conditions
• Aggregates data (sum, average, count by group)
• Merges multiple CSV files
• Converts to Excel with formatting applied

The filtering and aggregation features are particularly useful. Instead of importing a 10,000-row CSV into Excel and manually creating pivot tables, tell your agent to “summarize sales by region and product category, then output as an Excel table.” It handles the heavy lifting.

Example use: “Take this month’s transaction export, filter for amounts over $500, group by customer, and create an Excel file with totals.”

Install:

clawhub install csv-processor

spreadsheet-mailer

Generating a report is step one. Getting it to the right people is step two. This skill bridges OpenClaw Excel automation with email and messaging platforms.

What it does:

• Emails Excel files to individuals or distribution lists
• Posts spreadsheet links to Slack, Teams, or Discord channels
• Schedules automated report delivery (daily, weekly, monthly)
• Includes custom message text with attachments

The scheduling feature means you can set up a weekly sales report once and forget about it. Your agent generates the Excel file every Monday at 9am and posts it to your team’s Slack channel automatically.

Example use: “Email the monthly expense report to [email protected] with subject line ‘January 2026 Expenses’ and a summary paragraph.”

Install:

clawhub install spreadsheet-mailer

data-validator

Before you trust a spreadsheet, you need to know the data is clean. This skill checks for common data quality issues in Excel files.

What it does:

• Validates data types (numbers in numeric columns, dates in date columns)
• Checks for missing values and blank cells
• Detects duplicates
• Flags outliers and anomalies
• Verifies formula consistency

Run this skill on any incoming data before processing it further. It catches issues like text values sneaking into numeric columns, duplicate customer records, and formula errors that break downstream calculations.

Example use: “Validate this inventory file and flag any missing SKU codes or negative quantities.”

Install:

clawhub install data-validator

Real Workflow: Monthly Financial Close

Let’s walk through a complete workflow that a finance team might run using OpenClaw Excel skills.

The old way:

1. Export transactions from the accounting system (5 minutes)
2. Open the monthly close template in Excel (1 minute)
3. Import the transaction data (5 minutes)
4. Apply formulas for each expense category (10 minutes)
5. Create pivot tables for department breakdowns (10 minutes)
6. Format the report with conditional formatting and charts (15 minutes)
7. Calculate variance vs. budget (10 minutes)
8. Write a summary paragraph (10 minutes)
9. Export to PDF and email to leadership (5 minutes)

Total: 71 minutes of work. Most of it is mechanical.

With OpenClaw Excel automation:

You send your agent this message in Telegram:

Generate the monthly close report for January 2026.
Use the standard template.
Include expense breakdown by department,
variance analysis vs. budget,
and trend charts for the last 6 months.
Email the PDF to [email protected] with a summary.

Behind the scenes, your agent:

1. Calls excel-automation to fetch the transaction data from your accounting API
2. Applies the formulas from your saved template
3. Generates pivot tables for department expenses
4. Adds conditional formatting to highlight over-budget categories
5. Creates trend charts using the last six months of data
6. Calculates variance and flags significant changes
7. Drafts a summary paragraph highlighting key insights
8. Exports the finished report to PDF
9. Calls spreadsheet-mailer to email it to leadership

Total time: 3 minutes. You spend zero minutes on copy-paste and formatting. Your only work is reviewing the summary before it sends, if you want to add context.

Connecting OpenClaw to Your Data Sources

OpenClaw Excel skills need data to work with. That data usually lives in other systems: CRM, ERP, accounting software, databases, or cloud storage.

CRM Integration

If your sales data lives in Salesforce, HubSpot, or Pipedrive, OpenClaw has skills for those platforms. Combine a CRM skill with excel-automation to pull fresh data and build reports in one command.

Example: “Pull all opportunities closed this quarter from Salesforce and create an Excel report grouped by sales rep with win rates.”

Check the Productivity category for CRM-specific skills.

Cloud Storage

Google Sheets, Excel Online, and Dropbox all have OpenClaw skills. Your agent can read from shared spreadsheets, update them, and save new versions without manual downloads.

For teams that store templates in Google Drive, this is critical. Your agent fetches the template, fills in the current month’s data, and saves the completed file back to Drive — all while you’re doing something else.

Database Queries

If your raw data sits in a SQL database, the database-query skill lets your agent run SELECT statements and pipe the results directly into Excel. No more exporting CSVs and importing them manually.

Example: “Query the sales database for January revenue by product and create an Excel pivot table.”

Tips for Better OpenClaw Excel Workflows

We’ve watched teams adopt OpenClaw Excel automation over the past few months. Here’s what separates smooth rollouts from frustrating ones.

Save templates as reference files. Instead of describing your entire spreadsheet structure every time, save a template with headers, formulas, and formatting. Tell your agent to “use the monthly_sales_template.xlsx file and fill in this week’s data.” It applies your existing structure to new data.

Use descriptive file names. When your agent generates spreadsheets, name them clearly: “Sales_Report_2026-01-31.xlsx” instead of “report.xlsx”. This matters when you’re generating multiple reports per week and need to find the right one later.

Test with small datasets first. Before automating your entire monthly close process, test your workflow with one week of data. Make sure formulas work, formatting looks right, and the output matches your expectations. Once it works on a small scale, scale up.

Combine skills in sequences. Use csv-processor to clean and aggregate data, then feed the result to excel-automation for formatting and charting. Chaining skills together handles complex workflows that a single skill can’t do alone.

Set up scheduled reports with caution. Automated delivery is powerful, but double-check your logic before scheduling weekly or monthly reports. A formula error that goes unnoticed in an automated report can compound over time. Run manually for a few cycles, verify accuracy, then automate.

For more on chaining skills together, the flowmind skill builds repeatable workflows. Once you’ve dialed in a process, save it as a flow and trigger it with a single command.

Limitations and What Excel Automation Can’t Do

OpenClaw Excel skills handle a lot, but they’re not a full replacement for hands-on spreadsheet work.

Complex conditional logic is harder to describe. Simple formulas work great. Nested IF statements with multiple conditions can be tricky to specify in natural language. For highly conditional logic, it’s sometimes faster to build the formula once in Excel and save it as a template.

Visual design requires iteration. Your agent can apply conditional formatting and generate charts, but if you need pixel-perfect layout or custom chart styling, expect to refine the output manually. Think of the agent as producing a solid draft that you polish, not a finished design.

Macros and VBA aren’t supported. OpenClaw Excel skills don’t run VBA macros. If your existing workflow depends on macros, you’ll need to translate that logic into skill commands or keep running those macros manually. Python-based alternatives via OpenClaw skills can often replace VBA functionality.

Real-time collaboration isn’t built-in. OpenClaw works by generating or updating files. If you need multiple people editing a spreadsheet simultaneously, stick with Excel Online or Google Sheets collaborative editing. The agent can update the file between editing sessions but doesn’t provide live co-authoring.

Large datasets take time. Processing a 100,000-row CSV file into a formatted Excel report isn’t instant. Your agent will do it, but expect a few minutes of processing time. For massive datasets, database tools or BI platforms may be faster than spreadsheet-based workflows.

None of these are deal-breakers. Most business teams use OpenClaw Excel automation for structured, repetitive tasks — exactly where it excels.

FAQ

Can OpenClaw work with Excel files stored on SharePoint?

Yes, if you have the office365 skill installed. It authenticates with your Microsoft account and can read, write, and update Excel files stored in SharePoint or OneDrive. Your agent treats them like any other Excel file.

What about Google Sheets instead of Excel?

The google-sheets skill provides similar functionality for Google Sheets. Most OpenClaw Excel workflows translate directly to Sheets. If your team uses Google Workspace, install google-sheets instead of excel-automation and the commands work almost identically.

Do I need Excel installed locally?

Not necessarily. The Excel skills use libraries like openpyxl (Python) or exceljs (Node.js) to manipulate spreadsheet files programmatically. Your agent generates Excel files without needing Microsoft Excel installed. However, if you want to open and review the files afterward, you’ll need Excel, LibreOffice, or Google Sheets.

Can OpenClaw handle pivot tables?

Yes. The excel-automation skill can create pivot tables from raw data. Specify which fields to group by, which to aggregate, and what calculations to apply. The output is a standard Excel pivot table you can refresh and modify.

How secure is this for financial data?

OpenClaw runs on your infrastructure. If you’re concerned about data security, deploy your agent on a private server or VPC. Data doesn’t leave your environment unless you explicitly send it somewhere. Skills that connect to third-party services (like cloud storage) use OAuth or API keys, which you control. Check the Security category for skills focused on data protection.

What happens if a formula breaks?

Your agent will report the error. If a formula references a cell that doesn’t exist or uses an invalid function, the Excel library throws an error, and your agent tells you what went wrong. Fix the formula in your template or command, then retry. The data-validator skill catches some common formula errors before they break your report.
