Frequently Asked Questions

Can I compare files in different formats?

Yes, you can compare CSV vs Excel, JSON vs CSV, or any combination. The tool normalizes data for comparison.

How do I handle numeric differences?

Set a numeric threshold to treat values as equal if they are within a certain tolerance (e.g., 0.01 for currency).

Can I map columns with different names?

Yes, use the column mapping feature to specify which columns should be compared between the two files.

Is there a file size limit?

The tool handles files up to several MB. Very large files may be slower to process in the browser.
