JSON to CSV
Convert a JSON array of flat objects to CSV.
Processed on your device. Your files and text are not uploaded.
Nested objects are rejected. Spreadsheet applications may interpret cells starting with =, +, -, or @ as formulas; review untrusted data before opening.
How to use
Paste your input, choose an operation, then copy or download the result.
When to use JSON to CSV
Export a flat collection of records as a table. The output includes every key found across the records, with blank cells for missing or null values.
Practical example
[{"name":"Asha","city":"Mumbai"},{"name":"Sam"}] creates name and city columns; Sam’s city cell is blank.
Can I convert nested objects?
This tool rejects nested objects and arrays. Flatten them into separate columns first. When opening untrusted CSV in spreadsheet software, inspect values that could be interpreted as formulas.
