- People cleaning small JSON, CSV, or YAML files
- Worth noticing
- A Web Worker handles UTF-8 text locally, with a stated 10 MiB limit and five delimiter choices.
Field notes
The homepage exposes seven separate operations rather than presenting one generic converter: JSON and CSV transformations, YAML-to-JSON, JSON formatting and validation, and CSV cleanup. Input can be pasted or opened as a UTF-8 file, then adjusted through controls for delimiters, indentation, nested-key flattening, duplicate rows, and formula protection. The site states that processing runs in a browser Web Worker and accepts up to 10 MiB per operation; CSV-to-YAML is not supported.
