Frequently asked questions
Can CSV preserve spreadsheet formatting?
No. CSV stores text values and delimiters, not fonts, colors, multiple sheets or full workbook behavior.
Is my content sent to a server?
No. Processing runs inside your browser. Optional editor recovery saves a draft on this device only. Read the privacy policy.
Will my original file be changed?
No. Downloaded results are separate copies. Open the finished output before sharing it or deleting an original.
