Xlsx For Ai
Exposes 37 tools for working with Excel files through MCP. You get the obvious read/write/diff operations, plus structural introspection that pandas drops on the floor: named ranges, data validations, conditional formatting, pivot table definitions, slicers, embedded images, form controls, and VBA macro detection. The `xlsx_doctor` tool runs a one-shot health check for macros, external links, and hidden sheets. Compute layer includes filter, aggregate, sort, and pivot operations that run server-side. Installs globally via npm, registers via stdio transport, and auto-provisions an anonymous client UUID on first use. Free tier available. Useful when your agent needs to preserve Excel semantics instead of flattening everything to CSV.

xlsx-for-ai
Short name: xfa — a real CLI command (xfa <file>, xfa samples, xfa --version) and the prompt shorthand (e.g. "use xfa to read this file"). Same entrypoint as xlsx-for-ai; matches the internal xfa_* / XFA_* brand surface.
Verified values, preserved structure, up to 100MB
The missing reliability layer for spreadsheet work in LLM agents. Read, write, diff, validate, and analyze .xlsx files end-to-end — with merged cells, formulas, named ranges, conditional formatting, pivots, and charts preserved.
