File Conversion

CorsProxy can convert CSV, XML, and RSS to JSON on the fly.

Business plan required: input and output require a Business plan and a valid API key.

Convert to JSON

Explicit input format

https://corsproxy.io/?url=https://example.com/data.csv&input=csv&output=json

https://corsproxy.io/?url=https://example.com/feed.xml&input=rss&output=json

Auto‑detect input

If you only set output=json, CorsProxy will auto‑detect the input format:

https://corsproxy.io/?url=https://example.com/data&output=json

CSV delimiter override

https://corsproxy.io/?url=https://example.com/data.csv&input=csv&output=json&delimiter=;

Response content type is application/json;charset=UTF-8.

Common errors

• Invalid input: input must be csv, xml, or rss.
• Invalid output: output must be json.
• Auto‑detect failed: if output=json without input and the format can’t be detected.
