Q1: Are these spreadsheet tools free?

Yes. Every tool is free to use with no sign-up and no limit on how often you use it.

Q2: Is my data uploaded anywhere?

No. The tools run in your browser, so your spreadsheets and pasted data never leave your device.

Q3: Which files can I use?

Excel files (.xlsx and .xls), CSV and TSV files, or data pasted straight from Excel or Google Sheets.

Q4: Do I need Excel installed?

No. The tools do the job in the browser and give you the result to download as Excel or CSV. Each one also shows the Excel formula that would do the same, if you want to learn it.
