Stream a bounded CSV or JSON import and report what an importer would actually find in it: the type families each column holds, how much of it is null, which records drift from the declared shape, which object keys are set twice, and what the file's encoding and line endings are.
This walkthrough uses the tool's public README and checked-in example files. Run the command from a repository checkout with Node.js 22+; inspect the source before using it on your own files.
Run the checked-in example
npm install github:edilec/csv-json-import-profilerRead the result
This installs the public GitHub source; csv-json-import-profiler is not published to npm.
Where this check stops
This local walkthrough does not establish the state of a live production system or replace the limits documented in the repository.
Before adapting the command to your own workflow, review the accepted inputs, exit codes and safety boundaries in the README.
