SheetShift by 4AM Edge

Free PDF→Excel / spreadsheet toolkit: an open MCP server plus a submission-ready ChatGPT plugin (MIT). Upload a document, get a spreadsheet back — no account, no paywall, no daily conversion limits.

What it does

SheetShift converts documents into spreadsheets through five stateless tools. Use it three ways: as a ChatGPT plugin, as an MCP server you add to your own AI client, or through the hosted site at https://sheetshift-unwindmeinstead-gmailcoms-projects.vercel.app.

All five tools are free, complete, and require no account or sign-in. The tool list is also returned live from the MCP server.

Use it in your AI client

Point your client at the public MCP endpoint:

https://sheetshift-unwindmeinstead-gmailcoms-projects.vercel.app/mcp

Claude Code:

claude mcp add --transport http sheetshift https://sheetshift-unwindmeinstead-gmailcoms-projects.vercel.app/mcp

Codex CLI:

codex mcp add --transport http sheetshift https://sheetshift-unwindmeinstead-gmailcoms-projects.vercel.app/mcp

No key, no OAuth — the endpoint is open.

Live site

The hosted tools and an email list live at https://sheetshift-unwindmeinstead-gmailcoms-projects.vercel.app.

Input limits

  • PDF inputs: max 50 pages, max 10 MB (text-layer PDFs only; scanned images without a text layer return a clear error — OCR is not part of this build).

  • Single file per call.

These caps exist because the serverless host has a ~10-second execution timeout; oversized input gets a clean error, not a hang.

Run it locally

Requires Python 3.12.

pip install -r requirements.txt

Each tool module under sheetshift_lib/tools/ is dependency-light (stdlib + pypdf + openpyxl) and runs standalone via its __main__ self-test, e.g.:

python -m sheetshift_lib.tools.pdf_to_xlsx

Agents / API tier

Machine callers can use the same tools over a pay-per-call API at /api/agent/*, metered in USDC on Base at $0.01 per call (x402). Human-facing tools through the plugin, the MCP endpoint, and the site are free with no limits.

Compliance note

The ChatGPT plugin is a free, complete tool: no pricing, no subscription or upgrade language, no checkout links, and no email capture inside the plugin. The plugin's only external link is an informational plans page. Details in terms.html / privacy.html on the site.
