AI Tells You What to Do.
You Still Have to Do It.
ChatGPT gives you a formula. Copilot writes a script. Then you spend 30 minutes figuring out where to put it, debugging edge cases, and reformatting the output.
You're Still Doing the Work
- 1Ask AI: "How do I calculate weighted average across sheets?"
- 2Get a formula. Copy it. Paste into cell. Wrong sheet reference.
- 3Go back to AI. Explain the error. Get a revised formula.
- 4Paste again. Works for one cell. Manually drag to fill 200 rows.
- 5Now format the results. Then build the chart. Then fix the labels...
You Describe. It Executes.
- 1"Calculate weighted average across all department sheets and add a summary chart"
- 2Agent reads your workbook structure, writes formula-driven code, executes it — no hard-coded values
- 3Results appear in your spreadsheet. Chart is created. Formatting applied.
Not an Assistant. An Executor.
ExcelMaster doesn't just suggest — it reads your data, writes code, runs it, verifies the output, and retries if something goes wrong. Fully autonomous.
Real-Time Execution
Describe what you need in plain language. ExcelMaster writes VBA or Python, executes it directly in your workbook, and you watch the results appear cell by cell.
Full Transparency
Every action the agent takes is visible. You see the code it writes, the cells it modifies, and the reasoning behind each step — in a sidebar right next to your spreadsheet.
Built-in Safety & Audit Trail
Every operation starts with an automatic backup. If the agent makes an error, it rolls back and retries. You can restore to any checkpoint, and every change is logged for full auditability.
One Prompt. Real Results.
From financial modeling to data cleanup, ExcelMaster handles complex multi-step tasks that would take hours manually.
From Raw Data to Full Model
Creates the revenue forecast, calculates WACC, builds the DCF table with terminal value, adds sensitivity analysis — all formula-driven and dynamically linked. Change one assumption, every cell updates.
10,000 Rows, One Command
Scans your dataset, normalizes inconsistent formats, deduplicates intelligently, and applies conditional formatting to highlight issues.
Board-Ready Reports in Minutes
Aggregates data from transaction sheets, builds structured P&L rows, adds subtotals, applies professional formatting, and creates comparison charts.
Complex VBA, Zero Debugging
Generates production-quality VBA that loops through sheets, maps columns dynamically, handles edge cases, and runs immediately — no manual editing needed.
ExcelMaster saved me 3 hours of manual formatting every week. I just describe what I need, and it does everything inside my spreadsheet.
I was skeptical about AI in Excel, but ExcelMaster actually executes the code. No more copy-pasting formulas from ChatGPT.
The auto-backup feature gives me confidence to let the AI work on important spreadsheets. One-click restore is a lifesaver.
Three Steps to Automation
Install the Add-in
Download and run the installer. ExcelMaster appears as a tab in your Excel ribbon. No configuration needed.
Describe Your Task
Open any workbook and click ExcelMaster. Type what you need in the chat sidebar — plain English or Chinese.
Watch It Execute
The agent analyzes your data, writes code, runs it, and delivers results. You see everything happen live.

Common Questions
ChatGPT and Claude give you formulas or code snippets that you need to manually copy, paste, and debug. Copilot can make edits but cannot run VBA or Python. ExcelMaster does the full loop: it reads your data, writes code, executes it inside your Excel, verifies the result, and fixes errors automatically.
ExcelMaster runs as a local add-in on your machine. Your raw spreadsheet files are never uploaded. When the agent needs to analyze your data, only the relevant cell content is sent to the AI model for processing — your full files stay on your machine. All API communication is encrypted in transit.
ExcelMaster supports Microsoft Excel 2016 and later on Windows 10/11. It requires the desktop version of Excel (not the web version).
ExcelMaster automatically creates a backup before every operation. If anything goes wrong, it can roll back to the exact state before the change. You can also manually restore to any previous checkpoint at any time.
ExcelMaster understands natural language prompts in English and Chinese. You can describe tasks in whichever language you are comfortable with.
No. ExcelMaster generates and executes code automatically. You just describe what you want in plain language. However, if you do know VBA or Python, you can review and modify the generated code before execution.
