Common questions
Which sheet is converted?
The first sheet in the workbook. Multi-sheet selection is on the roadmap.
What happens to formulas?
The computed values are exported, not the formula text.
Is my file uploaded anywhere?
No. The file is parsed and processed entirely in your browser using JavaScript. It never leaves your device, and nothing is stored on our servers.
