Frequently Asked Questions
What types of files can I edit?
This tool works with CSV (Comma Separated Values) and TXT files. First rows are treated as column headers.
Is there a file size limit?
Since processing happens in your browser, large files may affect performance. We recommend files under 5MB for optimal experience.
Will my formatting be preserved?
The CSV editor preserves data but not formatting like colors or cell styles. Downloaded files will be in standard CSV format.
Can I save my progress while editing?
Currently, we don't offer saving in-progress work. Complete your edits in one session and download the final CSV file.
