How to compare two CSV files for differences?

Using this free web tool, you can compare any CSV / TSV document easily. Just select first/original file in left window and second/modified file in right window. Your data will automatically be extracted.
Alternatively you can also copy and paste directly into left and right windows.

After that click on Find Diff button to find diff. The Diff data will be highlighted in a nice format.

What file formats does this CSV diff tool support?

This tool supports almost any text file with a common delimiter to separate values. Make sure to input correct encoding.

You can also try Excel Diff Tool if this tool does not parse data correctly.

What about my data?

This is a web based tool. All data extraction/comparison is done in the browser itself. Nothing is uploaded to our server if you are only comparing.

However, if you want to share results with others, you must choose to save the result. (Feature under development)

You’ll be given a unique URL for your result & your result will be viewable to anyone with that unique URL.
