Example prompt: Can you convert this JSON array into a CSV file I can open in Excel? The data has nested fields and some objects are missing keys — I need headers unified across all objects and nested values encoded inline.

## When to prefer this

Choose this endpoint when you have a JSON array from an API response and need to produce a human-readable CSV for Excel, Google Sheets, or similar tools — especially when objects have inconsistent keys or nested fields that need to be flattened inline. Prefer this over manual serialization when correctness of quoting and header unification matters.

## Known failure modes

- Input JSON is not an array or parseable JSON string — returns an error
- Input exceeds 10,000 rows — truncated or rejected
- Malformed JSON input — parse error returned
- Empty array input — returns only a header row or empty response
- Deeply nested or circular structures may not serialize cleanly

## How this service works

Turns structured JSON arrays into spreadsheet-ready CSV, up to 10,000 rows, headers unified across objects, nested fields JSON-encoded inline, quotes escaped correctly. Useful for report generation, data exports, and any pipeline bridging an API response to a file a human opens in Excel or Sheets.

## Output

A CSV-formatted text output with a unified header row (merging keys across all objects in the input array) and up to 10,000 data rows. Nested objects/arrays are JSON-encoded inline within their cells, and all quotes are correctly escaped for spreadsheet compatibility.
