Frequently asked questions
How do I use it?
Choose your files and press “Convert to Excel”. When it finishes, download the result.
How does it work?
Each file becomes a worksheet named after the file. Values are kept as text exactly as written, so leading zeros (like phone numbers) are not lost.
Are there limitations?
Because values stay as text, Excel may show a small “number stored as text” marker on numeric cells.
Are my files uploaded?
No. Files are processed on your device and never sent to our servers. No account is needed.
