Developer API
Call the same JSON/CSV-to-Excel conversion the web tool uses, directly from your own code — no browser, no clicking, rate-limited and metered per key instead of per human.
Endpoint
POST https://veqix61rpf.execute-api.us-east-1.amazonaws.com/dev/v1/convert
x-api-key: <your API key>
Content-Type: application/json
{"data": [{"name": "Alice", "age": 30}, {"name": "Bob", "age": 25}]}
Returns a binary .xlsx file (same output as the web converter, including headers and formatting). A single JSON object is automatically wrapped in an array.
Example
curl -X POST https://veqix61rpf.execute-api.us-east-1.amazonaws.com/dev/v1/convert \
-H "x-api-key: YOUR_API_KEY" \
-H "Content-Type: application/json" \
-d '{"data": [{"name": "Alice", "age": 30}]}' \
-o converted.xlsx
