csvdiff is a fast diff tool for comparing CSV files. It finds out the additions and modifications.
It is not a traditional diff tool. It is most suitable for comparing CSV files dumped from database tables. The diff tool is orders of magnitude faster on comparing line by line.
This is free and open source software.
Key Features
- Supports additions, modifications, deletions, and non comma separators.
- Supports selective comparison of fields in a row.
- Supports specifying group of columns as primary-key i.e uniquely identify a row.
- Support ignoring columns e.g ignore columns like created_at timestamps.
- Compares CSVs of million records in under 2 seconds.
- Supports lots of output formats e.g colored git style output or JSON for post-processing:
- diff: Git’s diff style.
- word-diff: Git’s
--word-diffstyle. - color-words: Git’s
--color-wordsstyle. - json: JSON serialization of result.
- legacy-json: JSON serialization of result in old format.
- rowmark: Marks each row with ADDED or MODIFIED status.
