See what changed between two product files.

Compare a previous catalog export with a newer one before you import or send it to another sales channel. Find added, removed, or changed product rows without checking each file side by side.

Free browser tool: select two CSV files to compare. Their contents stay in this browser tab and are not uploaded or saved by this tool.

1 · Choose the two delimited files

Previous file

For example, the last catalog export you trust. UTF-8 and BOM-marked UTF-16 text files are supported.

Current file

For example, the file you are about to update or submit.

Product matching column

Choose a unique, populated ID or SKU. Duplicate or blank keys stop the comparison.

No files are loaded.

2 · Review the differences

Include formatting-only changes in the table (for example, spaces or 15 vs 15.00). The downloaded report includes all differences.

What is checked?

Rows match by the selected exact ID/SKU after trimming outer spaces. Both files need unique, nonblank keys. Column order does not matter; headers match without case sensitivity. Shared columns are compared; columns present in only one file are listed separately and not compared. Price/quantity-like numeric fields with the same numeric value but different spelling, outer spaces, or line endings are classified as formatting-only. All other raw value changes are shown as data changes. This tool does not validate a marketplace specification or guarantee import/feed/listing success.

Removed rows may reflect different export filters or snapshots, not an actual deletion. Check that both files cover the same products before acting on removals.
