The reason to buy
What this saves you from building
You are not paying for a file count. You are skipping the failure handling, verification, documentation, and operational edge cases behind the feature.
Typed normalization and row checks
Use the documented CLI behavior and examples as a focused starting point.
Clean output and safe error reporting
Run the included tests and synthetic example before using your own data.
What's included
Connected infrastructure, ready to adapt
- Exact CSV column mapping
- Scalar normalization and row validation
- Within-file duplicate checks
- Validated JSONL output
- Value-free errors.csv and SHA-256 report
- Synthetic examples, tests, license and support terms
Typeset output evidence
Inspect the CLI, data, and QA results.
One card typesets verified output from the included synthetic local demo. This CLI kit has no browser UI.
Architecture
A small, inspectable workflow
Each step has a clear responsibility and can be adapted without turning the kit into a platform dependency.
