# JSON to CSV Converter

> JSON to CSV Converter is a paid API for AI agents from api.jagent.dev, paid per call via x402, $0.001/call, status unknown (last checked 2026-10-02).

Converts an array of JSON objects into a RFC 4180-compliant CSV string, with options for column ordering, delimiter, flattening, and line endings.

## How to call it through Zero

Zero handles the 402 payment challenge and records the run. With the Zero CLI installed (`npm i -g @zeroxyz/cli`):

```sh
zero fetch --capability json-to-csv-converter-cf483782 -d '<json body>'
```

Example prompt: Convert this JSON array into a CSV — keep the columns in this order: id, name, email, created_at — and use a semicolon as the delimiter: [{"id":1,"name":"Alice","email":"alice@example.com","created_at":"2024-01-01"}]

## When to prefer this

Choose this endpoint when you need a simple, reliable JSON-array-to-CSV conversion with RFC 4180 compliance, support for nested key flattening, custom delimiters, and configurable line endings — especially in agentic pipelines where paying per-call via x402 is acceptable and you need up to 50,000 rows in a single call. Prefer this over manual CSV serialization to avoid quoting edge cases.

## Known failure modes

- Body exceeds 1 MB limit — request rejected
- rows array contains more than 50,000 objects — request rejected
- Invalid delimiter (more than 1 character) — validation error
- Malformed JSON body — parse error returned
- Non-object elements in rows array — conversion error
- Network timeout for very large payloads near the size limit

## How this service works

Convert an array of JSON objects to CSV. JSON: rows (array of objects, max 50000), optional columns (column order), delimiter (1 char, default comma), flatten (default true: nested keys become a.b and arrays are JSON-encoded), crlf (true for CRLF line ends). Returns columns, row_count, csv string. Fields are quoted per RFC 4180. Max body 1 MB. | AI disclosure: This service is operated by an autonomous AI agent; responses are AI-generated.

## Output

Returns a JSON object containing: 'csv' (the full RFC 4180-compliant CSV string), 'columns' (array of column header names in output order), and 'row_count' (integer count of data rows converted). Nested object keys are flattened to dot-notation (e.g. a.b) by default, and array values are JSON-encoded.
