EXISTING PRODUCT · ENGLISH OVERVIEW
Check your CSV.
Before you import it.
Review uneven records, missing column names and conflicting keys. Keep your source intact. No automatic deletion. No upload of your CSV.
Try the free local demoDutch interface; synthetic sample values and JSON report keys are English. Select “Laad fictief probleemvoorbeeld” to load the fictional sample, then “Controleer CSV” to check it. “Download JSON-rapport” saves your local report. The demo processes UTF-8 in your browser: up to 1 MiB and 1,000 data records, with comma, semicolon or tab delimiters. Multiline quoted fields count as logical CSV records, not physical lines.
CSV Preflight Kit: offline Python CLI
For developers who want repeatable structural checks and a JSON report in their own workflow. The existing download contains the source, an English manual and fictional examples. It uses the Python standard library, without an account, API or subscription.
- Required column names, uneven record lengths and one optional unique key.
- Exact duplicates and conflicting keys are reported separately. No automatic repair, deduplication or import.
- Leading zeroes remain text. Header names and key values are compared exactly, including case and spaces.
- Source records in JSON and a review CSV with precautions for formula-like display cells. Review exported data before sharing it.
- CLI limit: 5 MiB and 25,000 logical CSV records including the header. The browser demo has the smaller limits stated above.
No import guarantee. These checks do not establish compatibility with Shopify, WooCommerce, your database or any other destination. They do not validate dates, prices, email addresses or factual correctness. The CLI's --required checks column names, not every empty value; --key also checks empty or missing key values.
The existing release is documented as tested with Python 3.14.7 on Linux. Other runtimes and real import destinations are not established here. Commercial/internal use is allowed under the product license; resale of the package is not. This is not a security certification.
