Limits before using it

Comma-separated UTF-8 CSV only, 1 MiB / 2,000 records. No XLSX, automatic zero recovery, Shopify integration, server authorization or database rollback. The host must validate and authorize all real writes. Currency is a label; no FX conversion.

Rejected CSV prefixes formula-like text with an apostrophe, intentionally changing it. JSON keeps strings; spreadsheet software may still coerce IDs on CSV opening. Input and receipts may contain private data: review before sharing.

Established alternatives

ImportCSV has a free React frontend. Papa Parse supplies this demo’s licensed parser. Custom free policy code may already meet your needs. No universal superiority, buyer reviews, traffic or revenue claimed.

No visitor analytics, accounts or collection form installed. The host may retain access logs. The demo JS is extractable; the paid hypothesis is source integration convenience, not protected browser functionality.
