excel extraction

Give your agent an Excel workbook it can actually read.

Frenchie turns XLSX workbooks into sheet-by-sheet Markdown so your agent can inspect assumptions, compare tabs, and write the follow-up without a custom parser.

# Extracted Markdown

## Sheet: Summary

| Field | Value |
| ----- | ----- |
| ARR   | $4.9M |
| Risk  | Procurement delay |

## Notes

- Source file preserved as
  agent-readable Markdown.
- Your agent does the reasoning
  after extraction.

why it exists

Files first. Reasoning after.

A workbook is rarely one table. It has sheets, formulas, notes, merged cells, and totals spread across tabs. Most agent flows flatten that into a mess or skip it entirely.

Frenchie emits one Markdown section per sheet, with tables preserved and formulas represented next to their evaluated values where available.

quick start

Install skills and MCP tools together.

The installer configures the MCP server and installs the Frenchie skills alongside the MCP tools, so your agent has the callable tools and the instructions for when to use them.

01

Install Frenchie

$ npx @lab94/frenchie install --api-key fr_...

This writes the local stdio MCP config and copies the Frenchie skills into your project.

02

Ask your agent to extract

> Extract ./forecast.xlsx to Markdown with Frenchie

Your agent calls extract_to_markdown. Stdio results auto-save to .frenchie/<name>/result.md.

03

Reason over Markdown

XLSX extraction costs 0.5 credit per sheet, with a 0.5 credit minimum. XLSX files can be up to 50 MB. Results expire 30 minutes after first delivery.

questions

The practical bits.

Does Frenchie calculate Excel formulas?

Frenchie uses available evaluated values and preserves formula context where possible. It is not a spreadsheet calculation engine.

Are hidden sheets included?

No. Hidden sheets are dropped by default in v1.

Is Excel extraction priced by rows or cells?

No. XLSX extraction is priced by sheet: 0.5 credit per sheet.

Give your agent a real file.

Install Frenchie, drop in a DOCX, XLSX, CSV, TSV, or PPTX file, and see the Markdown your agent gets back.
