1. Start a session
Open ExcelGPT in your browser, sign in with a free account, and start chatting. The account keeps your history, credit usage, and saved work consistent across tools.
2. Upload your data
Drag in an .xlsx, .xls, or .csv file. ExcelGPT parses every sheet, detects headers, preserves formulas, and infers each column's type so the AI understands your data before you ask anything.
3. Ask in plain language
Describe what you want — "sum revenue by month", "flag duplicate emails", "write a VLOOKUP that pulls price from Sheet2". You get a verifiable result you can paste into Excel, Google Sheets, WPS, or LibreOffice Calc.
