Compare Square catalog CSVs before you import

Compare your latest Square Item Library export with your next import draft. Spot changed SKUs, prices and stock before the file reaches your catalog. The comparison runs in your browser.

Try the sample comparison

Keep a fresh export from the same Square catalog

  1. Export your Item Library and keep an untouched copy.
  2. Open your import draft as a separate file. Keep the original Token for each existing variation. Format SKU fields as text when editing in a spreadsheet so values such as 00042 keep their zeros.
  3. Load both CSVs into the comparison. Turn on the missing-item check if the draft is meant to cover the entire catalog.

See Square’s Item Library import instructions for file requirements and the separate steps for moving items between accounts.

Review location prices and availability

A base price can look right while a location price has changed. Review the price, stock and Enabled columns for each affected location. Check blank fields and unexpected headers against your export before importing.

Entering 0 in New Quantity sets that location’s stock to zero when you import. Leave the cell blank to keep the existing stock count.

Download the review CSV and resolve the rows that need attention. The comparison flags differences between the two files. Review the actual import in Square Dashboard using Square’s location price override guide where applicable.

Request a $49 catalog review pilot

The pilot covers one Square catalog and one pair of CSVs. You get a review CSV with the variation Token, source line, current value and draft value for each flagged change. Use it to check which prices, stock quantities and location settings need attention before importing.

Tell us what you’re changing and roughly how many variations and locations are involved. We’ll agree on a small masked sample to check that the exports contain the fields we need.

Questions people ask

How do I check a Square catalog CSV before importing it?

Export your Item Library and keep an untouched copy. Compare that export with your import draft and review every changed SKU, price, stock quantity and location setting before the draft reaches your catalog.

Why do my SKUs lose their leading zeros?

A spreadsheet can treat a SKU as a number. Format SKU fields as text when you edit the draft so values such as 00042 keep their zeros.

What happens if I enter 0 in New Quantity?

The import sets that location's stock to zero. Leave the cell blank to keep the existing stock count.

Do I need to keep the Token column?

Yes. Keep the original Token for each existing variation in your draft. The review CSV lists the variation Token, the source line, the current value and the draft value for each flagged change.

Does the comparison change my Square catalog?

No. It runs in your browser and flags differences between the two files. The import itself happens in Square Dashboard, where you review it.
