Can I reorder columns?

Yes — deselect all columns, then click them one by one in the order you want them to appear in the output.

Is my data uploaded to a server?

No. Everything runs locally in your browser using JavaScript. Your data never leaves your device.

Can I rename columns?

Not directly here. Use the CSV Editor to rename cells in the header row after extracting.

What happens to rows with empty values in extracted columns?

All rows are kept — empty values remain empty in the output.
