Frequently Asked Questions (FAQ) - Excel Protection

Q: What is the difference between Sheet Protection and Workbook Encryption?

A: Encryption requires a password to open the file. Sheet Protection allows users to view the data but prevents them from editing or overwriting protected areas.

Q: Can I change a password if I forgot the old one?

A: **Yes!** Our tool allows you to overwrite any existing sheet password with a new one without needing the original password.

Q: Is my Excel data safe with ITKB?

A: Absolutely. ITKB uses browser-side processing, meaning your file is never uploaded to our servers. Everything happens on your device.
