CSV Diff Checker: what it does
The checker compares corresponding cell positions, including the header row. When values differ, the report names the row and column and shows the value from each file. Extra rows or columns are reported too.
How to use it
Select exactly two CSV or TSV files and run the checker. It compares their contents in the order provided, so sort or align records first if you want like-for-like row comparisons.
What to check in the result
This is a positional diff, not a key-based record match. A row inserted near the top shifts later comparisons. To find complete records that exist only in one file regardless of position, use Compare Two CSV Files.
Frequently asked questions
Does row order matter?
Yes. Values are compared by their row and column positions.
Are source files changed?
No. The tool creates a separate difference report.
Can I compare two files with different row counts?
Yes. Extra rows and cells appear in the report.
