Frequently asked questions
Everything happens in your browser, so most answers come down to: it's private, free and instant.
Are formulas kept?
CSV can only hold values, so each cell's calculated value is exported.
Are my files uploaded?
No. The conversion runs inside your browser, on your device. Your files are never sent to a server, so it's safe for private photos and documents.
Is it free? Are there limits?
It's completely free, with no sign-up and no watermark. Convert as many files as you like — the only limit is your device's memory.
