About this tool
Turn a CSV export into a JSON array using the first row as field names. Quoted delimiters, doubled quotes and line breaks inside quoted cells are supported. Values remain strings so identifiers and leading zeroes are not silently changed.
How to use it
- 1
Paste CSV with unique column names in its first row.
- 2
Choose the delimiter and whether to skip blank rows.
- 3
Convert to JSON and review any row-length errors.
Questions, answered
How are numbers, dates and blank values handled?
Every cell remains a string, including empty strings. Automatic type guessing can damage postal codes, IDs and dates, so this tool does not perform it.
What if rows have different lengths?
Conversion stops with the row number and expected field count. Empty or repeated column names are also rejected to avoid dropping or overwriting data.
