## 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 tanod-docs-xlsx-to-json-97a56384 -d '<json body>'
```

Example prompt: Convert this Excel workbook to JSON for me — grab it from https://example.com/report.xlsx and return all sheets with their rows as structured data in json format.

## When to prefer this

Choose this endpoint when you need to extract structured row/cell data from Excel workbooks (.xlsx or .xlsm) as JSON or CSV, especially in automated pipelines where you want per-sheet arrays of string values. Prefer it over generic document converters when the output must preserve multi-sheet structure and cell-level granularity. The URL delivery option is useful when large workbooks would bloat your context window.

## Known failure modes

- File exceeds 20 MB (URL) or 10 MB (base64) size limit — request rejected
- Private, internal, or IP-literal host URLs refused
- Unsupported file format (non-.xlsx/.xlsm) — parse error
- Formula cells return empty string if file was never opened in a spreadsheet application
- Network timeout fetching remote URL
- Malformed base64 input — decoding error

## How this service works

Documents: DOCX template fill, Office to PDF, any file to Markdown, PDF to Word, OCR, PDF pipeline.

## Output

Returns a JSON object with the output format, operation name, input byte size, sheet count, and an array of sheets — each containing the sheet name, a rows array of string arrays, column count, row count, and a truncated flag. Optionally returns a download URL with expiry, byte size, content type, and SHA-256 hash instead of inline base64 content.

## Response schema (JSON Schema)

```json

CSV output is one file per sheet, UTF-8 with CRLF, and a cell that could be read as a formula is prefixed with an apostrophe (OWASP) so a spreadsheet cannot run it.",
