Common questions
Does this handle large CSV files?
It's built for typical exports, spreadsheets, and reports, generally up to a few thousand rows. Very large files (tens of megabytes) may feel slow since everything renders as real table cells.
Can I add or remove columns?
You can add columns and rows with the buttons below the table. To remove a column, clear its header and leave the cells blank, or edit the exported file directly.
What happens to my data?
It stays in your browser the whole time. Nothing is uploaded, and closing the tab clears it, so export before you navigate away.
