GEEDITOR / NDJSON → CSV
About this conversion · NDJSON → CSV
Prepare NDJSON data as CSV for an importer or script. Match the destination’s expected delimiter, row structure and treatment of identifiers before exporting the full dataset.
Use an array of objects or an array of row arrays. Object keys become columns; missing values become empty cells. Nested objects and arrays become JSON text inside a cell, not extra columns. Normalize a deeply nested structure before importing it as a flat table.
CSV and TSV export prefix formula-like text with an apostrophe to reduce spreadsheet formula execution risks. Inspect such cells during import; the prefix is deliberate, not a missing character in the source.
Worked example
Input
{"id":"0012","name":"A, B","meta":{"size":"M"}}
{"id":"0013","name":"C"}Output
id,name,meta
0012,"A, B","{""size"":""M""}"
0013,C,How to convert
- Click “Choose files” and select the original NDJSON file. Start with one file when comparing settings.
- Check that the output selector shows CSV. The instructions here describe this choice; changing the output can change which settings apply.
- Click “Convert files”, then save the result from its file row. “Download all” puts completed files into a ZIP; it does not combine their contents.
- Open the CSV result and compare row counts, headers, empty cells, dates and identifiers with the NDJSON source. Preserve codes such as 00123 as text in the receiving application; do not assume its automatic type detection is correct.
