Data Conversion · REST API

JSON to CSV & CSV to JSON API

Convert structured JSON records into CSV and parse CSV text into JSON arrays through two dedicated REST endpoints.

Free tier available. Both endpoints require a JWT Bearer Token.

Conversion capabilities

Choose semicolon, comma, pipe or tab delimiters for both directions.

Configure quote modes and quote characters to match your data exchange format.

CSV to JSON can infer data types, trim fields and preserve numeric-looking values with leading zeros as strings.

Send a JSON array of flat objects. The first object determines the CSV headers; missing fields become empty cells.

Endpoint

POST
					/api/v1/convert/data/json-to-csv

Input: application/json · Output: text/csv

Input

[
  {"username":"alice","age":28,"premium":true},
  {"username":"bob","age":31,"premium":false}
]

Output

username;age;premium
alice;28;true
bob;31;false

Optional JSON to CSV query parameters
Parameter	Default	Description
`delimiter`	`SEMICOLON`	COMMA, SEMICOLON, PIPE or TAB.
`quoteMode`	`NONE`	ALL, ALL_NON_NULL, MINIMAL, NON_NUMERIC or NONE.
`quoteChar`	—	DOUBLE_QUOTE, SINGLE_QUOTE or BACKTICK; ignored with quoteMode NONE.

Send raw CSV text with column headers in its first row. Empty fields become null; type inference can identify numbers, booleans and dates.
