CSV to JSON
Convert CSV headers and records to JSON.
Processed on your device. Your files and text are not uploaded.
Comma-separated input with a header row. Values remain strings; quoted commas, escaped quotes and multiline fields are supported.
How to use
Paste your input, choose an operation, then copy or download the result.
When to use CSV to JSON
Convert a comma-separated table into objects for an application or API. The first row supplies the keys, and every remaining row becomes an object.
Practical example
name,city followed by Asha,Mumbai produces [{"name":"Asha","city":"Mumbai"}]. A field containing a comma must be surrounded by double quotes.
Are numbers and dates converted automatically?
No. Values remain strings so leading zeros and date-like values are not silently changed. Headers must be unique and nonempty, and each record must have the same number of fields.
