Your data never leaves your device. All files are processed entirely in your browser using client-side JavaScript - no data is stored on our servers or sent anywhere. There's no account to hack, no database storing your files, and no API connections to your bank or accounting software. You upload, convert, download, and we forget it immediately.

No payment or signup required. You can upload your file, see a free preview of the conversion results, and verify everything looks correct before paying anything. If it doesn't work for your files, you haven't wasted any money. We only charge when you're satisfied and ready to download the final converted file.

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.

Go to Square Dashboard → Items & Inventory → Item Library → Export. Choose Excel format for best results (CSV may convert SKUs to scientific notation).

Each variation becomes a separate QuickBooks product using 'Item Name:Variation' format. Enable 'Combine Variations' to use this format.

QuickBooks doesn't allow duplicate SKUs. The converter warns about duplicates so you can fix them before import.

Enable 'Import Inventory Quantities' to set initial stock levels. Products with quantities become Inventory type; others become Service type.

Square uses > for category hierarchy (Apparel > T-Shirts). QuickBooks uses : instead. We convert automatically.

When exporting from Square as CSV and importing to QuickBooks, product prices are included in the import. However, price updates must be made manually in both systems—pricing changes in one system don't automatically sync to the other.

Products with duplicate names, variations, or special characters may fail to import. Ensure each product has a unique name, check your CSV file for formatting issues, and verify the import file matches QuickBooks' requirements.

No, the integration is one-way. Price changes made in QuickBooks do not update Square automatically. You must update prices in Square first, then export and re-import to QuickBooks if needed.

Sync with Square is retired and Connect to Square is being phased out. The current recommended solution is Square Connector by Intuit, which offers better compatibility, direct support, and more reliable product syncing with QuickBooks.

Square variations can't be imported directly into QuickBooks. Export your base items without variation details, then manually create separate items in QuickBooks for each variation if needed, or use the base product name.
