Workday EIB Toolkit — generate, validate, and diff Workday EIB load spreadsheets, locally and deterministically. Ships as a Python library, a CLI, and an MCP server so an AI assistant can do EIB prep with files-in/files-out — no tenant credentials involved.

Unofficial — not affiliated with, endorsed by, or supported by Workday, Inc. Works entirely on files you already have (EIB templates and load workbooks exported from your tenant). Nothing here connects to a tenant.

Why

Inbound EIB loads live or die by a spreadsheet. Practitioners lose hours to upload→fail→fix loops because Workday's staging errors are vague and row-anonymous, templates drift between releases, and multi-sheet spreadsheet keys are maintained by hand (see docs/RESEARCH.md for the survey with sources). This toolkit is the pre-flight layer that should have existed:

• Validate a filled workbook against its template before upload — typed, evidence-backed findings with sheet/row/column coordinates (bad dates, wrong reference-ID types, missing required fields, broken spreadsheet keys, encoding hazards).
• Diff two template generations to see exactly what a Workday release changed, or two filled workbooks to review a load like a code review.
• Generate a correctly-typed, correctly-keyed load workbook from a declarative load spec plus your CSV data — with an optional Claude assist that drafts the spec from natural language (Claude drafts and annotates; generation itself stays deterministic).

Status

Day 1 — scaffold. See docs/PLAN.md for the build roadmap and docs/RESEARCH.md for the landscape research this design is based on.

Roadmap

• Research + scaffold
• Core models + template/workbook parser
• Validation engine (evidence-backed findings)
• Generator + template/workbook diff
• CLI + MCP server (FastMCP)
• Synthetic fixtures + full test suite
• v0.1.0
