SKU Code Comparison Tool

This tool helps you quickly compare two lists of SKU codes and identify which items from one list (e.g. a product report, inventory list, or export from a system) are missing in another.

It's especially useful for:

• Retailers verifying stock against supplier data
• eCommerce managers matching catalog data from different platforms
• Warehouse or logistics teams checking inventory sync
• Anyone comparing product codes from Excel tables or CSV files

How to use:

1. Copy the list of SKU codes from Table 1 (reference list) and paste it on the left.
2. Copy the list from Table 2 (the list you want to compare against) and paste it on the right.
3. Click Compare and instantly see which SKUs from Table 1 are missing in Table 2.

The result will show missing codes in neat columns, making it easier to read—even with long lists. All comparisons are done right in your browser, with no data uploaded anywhere.
