How People Use Square Item Details
Square's item details export concatenates modifier names into the Variation Name column with inconsistent delimiters — sometimes a comma, sometimes a pipe character. The validator flagged 85 rows where the modifier formatting would have broken our cost-of-goods calculation in QuickBooks.
We had an item details CSV where the Qty column contained decimal values for items sold by weight, but our inventory system expects integers for count-based items. The validator caught 43 rows mixing weight-based and count-based quantities so we could split them before the import.
Square's tip allocation spreads across item detail rows in ways that throw off per-item Net Sales calculations. The validator identified 31 rows where Gross Sales minus Discounts didn't equal Net Sales because tips were embedded in the totals, letting us isolate tip amounts before feeding the data into our margin analysis.
Why Validate Item Details?
Line Item Accuracy
Item Details contain one row per product sold. Missing Transaction ID breaks the
link to the parent transaction.

Frequently Asked Questions
You can, but free scripts and AI often miss edge cases that break real-world data: missing SKUs, currency formatting quirks, tax calculation errors, or date format mismatches. We have battle-tested validators specifically designed for accounting software imports that catch these issues before they corrupt your books. Plus, you get instant browser-based conversion without installing Python or managing dependencies.
Only the Transaction ID column is required. It links to the Transactions export.
Item Details contains one row per line item and joins to Transactions via Transaction ID.
You can preview Square Item Details validation results for free — no signup needed. Full validation reports use credits based on row count.
Save your file as .xlsx or .csv format. The validator won't accept .xls, .xlsm, or other file types.
Some spreadsheet editors convert SKUs to scientific notation. Don't open the file directly in Excel; use a text editor instead to preserve formatting.
Items and their variations must have the same category and description. Ensure all variation names are unique within each item.
GTINs must be 8, 12, 13, or 14 digits long and contain only numbers 0-9. Remove any special characters or incorrect lengths.
Remove all commas from your file before importing. You can add them back to item names after the import is complete.
Each item in your library must have a unique name. Check for variations with identical item names and rename them.
All item variations using option sets must have both an option set name and an option value. Don't leave these fields blank.
