A file that was opened and re-saved in Excel is fine; the app strips what Excel adds to barcodes.
If something is missing, this is why. A listing with no barcode and no SKU cannot be printed — there is nothing to put in the code. Those are counted and named on the Labels and Sheets pages, so a missing item never looks like a bug. In Shopify, the free Retail Barcode Labels app assigns barcodes to variants that lack one: run it, export again, and they appear.
Re-import whenever stock or prices change in your POS. Your label layout, batch, and sheet order survive a re-import.

A letter page of names, prices, photos and big barcodes — for selling small things off a laminated sheet instead of grabbing each one.
On Settings, Update file writes an edited copy of your own export with only the rows that changed: prices you set here and, for Square, codes the app generated for items that had none. Import that file in your POS dashboard and it learns them. Import a fresh export here afterwards and the loop is closed.
