ExcelMaster.ai FAQ
What makes ExcelMaster different from ChatGPT or Copilot?+
ExcelMaster reads your actual workbook, writes full VBA/Python, executes it inside Excel, verifies results and auto-retries, whereas ChatGPT and Copilot only return code snippets.
Is my data safe?+
The add-in runs locally; only the relevant cell content is sent to the AI model and all communication is encrypted. Full files never leave your machine.
Which Excel versions are supported?+
ExcelMaster works on Microsoft Excel 2016 and later on Windows 10/11, desktop version only.
Can ExcelMaster break my spreadsheet?+
Before every operation it creates an automatic backup and can roll back to any checkpoint, preventing permanent damage.
How are credits consumed?+
Credits are deducted based on actual AI usage for each task; unused credits do not roll over to the next month.
Do I need an internet connection?+
Yes, to call the AI models, but your spreadsheet files stay on your local machine.
