Up to 10 MB, 200,000 rows, 300 columns, and 2,000,000 cells. Your file stays on this device. Changing the input or separator resets column names and types for review.

Result preview

Update the preview to inspect your rows. Then edit column names before downloading.

Broken quotes block export. Short rows are padded; extra columns receive names. Column types never change without your choice. Jobs stop after 12 seconds. Up to 10,000 cell issues can be reviewed at once.

Three simple steps

How to use it

  1. Open or paste the messy CSV and tell Bookify if the first row has headings.
  2. Choose the cleanup jobs, then select Update preview. Edit column names if needed and update again.
  3. Review the fixed table, then copy or download the clean CSV.
