BigCommerce local precheck
BigCommerce CSV Validator
Compare a target-store export with the CSV you plan to import. Both files stay in this browser tab.
Two UTF-8 CSV files, up to 15 MiB each; the planned import can contain up to 100 products. Catalog content is processed locally and is not uploaded or sent to a store API.
A · Target-store baseline export
Export this from the BigCommerce store that will receive the import.
Choose baseline CSV
CSV · UTF-8 · Up to 15 MiB
B · Planned import
This is the file that will be checked against the baseline.
Choose import CSV
CSV · UTF-8 · Up to 15 MiB
Confirm the file roles, names, sizes, and CSV format before starting. Selecting or replacing either file clears the previous result.
Supported scope and limits
Checks cover detectable file, template, product, variant, image, and field risks in the supported modern CSV shape: Product/Variant/Image rows and Options made of Type/Name/Value triples. Comparing a baseline does not teach the checker a different CSV dialect. The tool does not connect to BigCommerce, fetch remote images, read store settings, or predict the final importer result.
