Import Check Every row, your rules
Required fields, exact uniqueness, numeric bounds, allowed values and six column types.
CSV QUALITY · API + MCP · V0.1
Catch the bad rows.
Keep the import moving.
Validate a CSV against your rules. Find duplicates, missing values and invalid dates. Apply only the cleanup you choose, with a report you can review.
No account or card for the sample. Your files stay in processing memory and are not retained.
No silent guesses
Trim, change case, rename headers or convert explicit decimal commas. Review the validated output.
Built for repeatable work
The same deterministic engine in your browser, application and MCP client. Reuse a request ID for safe retries.

A few useful boundaries.
Does a valid report guarantee the destination will accept my file?
No. It means the CSV passed the schema you supplied. Import Check cannot see existing destination records or check your business rules beyond that schema. Test a small import first.
Do you support Excel files or infer my schema?
Version 0.1 accepts UTF-8 CSV and explicit schemas. Export Excel to CSV first. We do not guess dates, drop duplicates, evaluate formulas or send your file to an AI model.
Can I retry without paying twice?
Yes. Reuse the same request ID and identical arguments. The browser keeps the request ID for the same input during this tab's lifetime. Changed input requires a new ID.
Where are my files stored?
They are processed in memory and returned to you. We retain payment references, operation counts and retry fingerprints, not CSV contents or reports. Your MCP client may have its own retention policy.
