Which tool fits your CSV?

Product prices and stocks, or contact duplicate candidates? Check the actual copy and selected fields, then try the same first 20 rows without selecting a file again.

Check the task and actual CSV scope

Use a backup copy. Contents stay in browser memory: no upload, account connection, AI request, new analytics or persistent storage. Only headers and issue positions appear in results; source values are preserved.

Two different tasks and downloads

General product CSV checker: SKU, name, non-negative integer price/stock and image URL format. Up to 1,000 rows, 100 columns and 2 MiB. KRW14,900 seller price.
Contact CSV review: one mapped email and phone column; source, reviewed, candidate and issue CSVs. Up to 2,000 rows, 80 columns and 2 MiB. KRW19,900 seller price.

Both existing downloads have Korean and English interfaces and guides. This chooser checks the general tools. Decimal-price WooCommerce simple products need the separate companion scope guide (Korean); this general integer-price trial does not certify that companion.

Direct file opening, actual customer files, Excel/CRM imports and mobile use remain unverified. Free tools do not accept done-for-you cleanup, contracts, paid work or customer attachments. Final tax/amount and the existing order/support route appear at Lemon Squeezy.

Existing product CSV conditions (English) and contact conditions (English) apply. No new usage or refund terms are introduced.
