JavaScript Object to CSV Converter
Turn JavaScript object or array literals into CSV rows with delimiter control and header options.
Export JavaScript objects to CSV
Frontend fixtures, API mocks, and spreadsheet imports often start as JavaScript object literals rather than strict JSON. Paste an object or array of objects to produce CSV with a custom delimiter and optional header row.
For JSON input, use the JSON to CSV Converter. To go the other way, try the CSV to JavaScript Object Converter.
Frequently Asked Questions
Which JavaScript syntax is supported?
Unquoted object keys, trailing commas in arrays, and standard literals (strings, numbers, booleans, null) are supported. Functions and expressions are rejected for safety.
How are nested values exported?
Nested objects and arrays are JSON-stringified inside the CSV cell so rows stay rectangular.
