Description

Mixpanel is returning raw data in this format:

Data returned from this endpoint is JSONL (newline-delimited JSON). Most receiving client libraries will automatically assume it gets a JSON string back and attempt to decode it. This specific API does not return valid JSON in aggregate, but each row is valid JSON within the API's output. Thus, raw exports, once received in full, should be parsed line-by-line instead of as an array of JSON objects. https://mixpanel.com/help/reference/exporting-raw-data

Will this format be supported in the near future? Thanks

Research direction
Investigate how jsoneditor currently parses JSON input (likely in a core parser module). To support JSONL, the editor would need to detect that the input contains multiple JSON objects separated by newlines, then parse each line individually and present them as an array or separate entries. Look for existing parsing logic in the source code, possibly in files like 'src/treemode.js' or 'src/JsonParser.js'. The maintainer hasn't responded, so the contributor may need to propose a clear implementation plan. Consider adding a checkbox or format detection toggle in the UI.
