## 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-2b3d3ab4 -d '<json body>'
```

Example prompt: Convert this JSON array of sales records to a UTF-8 CSV file with columns in this order: id, date, product, amount, region — and warn me if any nulls are dropped or formulas need escaping.

## When to prefer this

Choose this endpoint when you need a deterministic, RFC 4180-compliant CSV from JSON rows with guaranteed column ordering and explicit handling of nulls and formula injection. Prefer it over generic converters when reproducibility and safety warnings (null-loss, formula escaping) are required, or when downstream consumers are spreadsheet tools like Excel or Google Sheets that are strict about CSV formatting.

## Known failure modes

- Nested objects or arrays in JSON cells are rejected — input must be a flat scalar matrix
- Null values are silently converted to empty strings with a warning rather than preserved
- Malformed JSON input returns a parse error
- Mismatched column order specification (columns not matching JSON keys) may cause missing or empty columns
- Formula injection characters (=, +, -, @) in cell values are escaped with a warning

## How this service works

JSON to CSV converter — export JSON rows to deterministic RFC 4180 UTF-8 CSV for spreadsheets and data export, using explicit column order or a scalar matrix. Returns byte/row counts, default formula escaping and null-loss warnings; null becomes empty text and nested cells are rejected.

## Output

Returns a UTF-8 RFC 4180-compliant CSV text output along with metadata including byte count and row count, plus warnings for any formula-injection escaping applied and any nulls converted to empty text; nested cell values are rejected with an error.
