GraphQL AccessALPHA

Access JSON to CSV Converter through GraphQL to combine it with other API calls in a single request. Query only the json to csv converter data you need with precise field selection, and orchestrate complex data fetching workflows.

Test JSON to CSV Converter in the GraphQL Explorer to confirm availability and experiment with queries.

Credit Cost: Each API called in your GraphQL query consumes its standard credit cost.

GraphQL Endpoint
POST https://api.apiverve.com/v1/graphql
GraphQL Query Example
query {
  jsontocsv(
    input: {
      json: [{"name":"John Doe","age":30,"city":"New York"},{"name":"Jane Smith","age":25,"city":"Los Angeles"}]
      delimiter: ","
      include_header: true
    }
  ) {
    row_count
    column_count
    columns
    csv
  }
}

Note: Authentication is handled via the x-api-key header in your GraphQL request, not as a query parameter.

CORS Support

The JSON to CSV Converter API accepts cross-origin requests from any origin, so it can be called directly from browser-based applications without a proxy. See CORS support →

JSON to CSV Converter requests are throttled per minute on the Free plan and unthrottled on paid plans. Exceeding the limit returns 429 Too Many Requests; rate-limit usage is reported in the X-RateLimit-Limit, X-RateLimit-Remaining, and X-RateLimit-Reset response headers. See per-plan limits and best practices →

Error Codes

The JSON to CSV Converter API uses standard HTTP status codes — 200 on success, 400 for invalid parameters, 401 for missing or invalid keys, 403 for insufficient credits, 429 for rate-limit exhaustion, and 500/503 for server-side issues. Each error response includes an X-Request-ID header you can quote when contacting support. See full error handling guide →
