Frequently asked questions
Are my files uploaded?
No. Every tool in this category runs inside your browser on your own device. Files are never sent to our servers, and nothing is stored after you close the page.
Are formulas kept?
Conversions between XLSX and XLS keep cell values and most formulas. CSV and JSON contain values only, by design.
How big can a CSV be?
Hundreds of thousands of rows work on most computers. The limit is your browser's memory, not our servers.
