CSV and JSON Converter
Convert CSV or TSV to JSON and JSON arrays to CSV using quoted-field parsing, header controls, type detection, table preview, and downloads.
Convert real quoted CSV and TSV instead of splitting on commas
CSV fields can contain commas, line breaks, and quote characters when enclosed in double quotes. Embedded quotes are represented by two consecutive quote characters.
ArrayText supports arrays of objects using a header row and arrays of arrays for headerless data. JSON objects with nested values are preserved as compact JSON strings inside CSV cells.
CSV and JSON Converter FAQ
Does the converter handle commas inside quoted fields?
Yes. The parser recognizes quoted fields and doubled quote escapes.
What happens when rows have different column counts?
Short rows are padded with empty cells and a warning asks you to review the table preview.
Can it convert TSV?
Yes. Choose Tab as the delimiter for tab-separated data.
