## How to call it through Zero

```

Example prompt: Convert this CSV string to a JSON array — it has a header row and I'm not sure if the delimiter is a comma or semicolon: 'name;age;city\nAlice;30;New York\nBob;25;London'

## When to prefer this

Choose this endpoint when you have a raw CSV string (not a file URL) and need a structured JSON array back without having to specify the delimiter yourself — especially useful for CSVs of unknown origin where the separator (comma, semicolon, tab, pipe) isn't guaranteed. It also saves a step by inferring numeric and boolean types automatically rather than returning all values as strings.

## Known failure modes

- Malformed or empty csv_string returns an error
- Ambiguous delimiter that cannot be auto-detected may cause incorrect parsing
- CSV with inconsistent column counts per row may produce unexpected output
- Missing required csv_string query parameter returns a 400-level error
- Very large CSV strings may hit size or timeout limits

## How this service works

Convert CSV string to JSON array with auto-detected delimiter and type inference. Algorithmic.

## Output

Returns a JSON array of objects where each row becomes a JSON object with keys from the header row (if present), and values automatically cast to their inferred types (numbers, booleans, strings, etc.)
