About this comparison tool
Detect meaningful CSV differences
The CSV tool compares records using selected columns rather than only their physical position. It is useful for inventories, exported orders, product catalogues and tabular logs.
Before comparing
Check that both files have header rows and use similar column names. Use a unique reference field where possible; otherwise two unrelated rows may be matched incorrectly.
Frequently asked questions
Can I use semicolon-separated or tab-separated files?
Yes. The tool detects common comma, semicolon and tab separators.
How do I compare reordered rows?
Select a shared ID or another reliable key column so row position does not affect the comparison.
