A raw products.json file is a nested structure - an array of products, each with its own nested array of variants and images. That shape is exactly what a theme needs to render a store, but it’s not something Excel or Google Sheets can open sensibly on its own.
This tool flattens that structure into rows: every variant becomes its own line, with the parent product’s title, vendor, tags and description carried along, plus the variant’s own price, SKU and options. The result is a normal CSV you can filter, sort and pivot like any other spreadsheet.
You can either drop a saved products.json file directly, or paste the store’s URL above and skip the manual download step entirely.
Both paths end at the exact same output - a flattened CSV with one row per variant - so the choice between dropping a file and pasting a URL comes down to convenience, not capability. If you’ve already got the file downloaded for another reason, dropping it in is one step faster than fetching it again.
