About Excel to CSV
Formulas and formatting
CSV and JSON store values only. Cells with formulas export their last calculated value; colors, merged cells and charts are not included.
Your files never leave your device
Most online PDF sites upload your documents to their servers. DocuVault doesn’t. Everything happens inside your browser, so there is nothing for anyone to see, store or leak.
Check it yourself
Use a tool once, then turn off your Wi-Fi or switch to airplane mode and use it again — it still works. Developers can watch the Network tab: no file is ever sent.
Step 1
You choose a file
Your browser opens it directly from your device — like opening it in an app.
Step 2
Your device does the work
The processing code runs inside this browser tab. No server ever receives your file.
Step 3
You save the result
The new file goes straight to your downloads. Close the tab and everything is gone.
Frequently asked questions
Can I convert a specific sheet?
Yes. Pick the worksheet tab you want before downloading.
Will Excel open the CSV correctly?
Yes. The CSV includes a UTF-8 marker so Excel shows accents and non-English characters correctly.
