JSON preview

Upload or paste CSV data and choose parsing options to prepare a JSON output preview.

Choose a CSV file or table input, set delimiter and header behavior, and select the JSON layout you want to prepare.

Are CSV files uploaded?

No. This frontend-only page does not send selected files or table data anywhere.

Does it convert data yet?

The current version implements the complete interface only; parsing can be added later in browser JavaScript.
