CSVProof, for the CSV handoff that has to be right
CSVProof presents a desktop CSV editor for inspecting, changing, comparing, and exporting files without hiding how values are interpreted.
- For
- People checking or reconciling business CSV exports
- Worth noticing
- Its preview keeps identifiers such as 001234 as text and shows keyed-comparison counts for unchanged, added, removed, and changed records.
Field notes
The product preview stages a local vendor CSV with 12,481 rows and six columns, then shows cell editing, calculated columns, transformation steps, keyed comparisons, and an issue-review queue. Example operations include trimming whitespace, mapping country codes against a lookup file, and filtering active records; comparison output separates unchanged, added, removed, and changed rows. The page describes CSVProof as private early access for macOS and Windows, so the interface and sample counts are homepage evidence rather than confirmation of shipped behavior.
