witan-xlsx-mcp

witan-xlsx-mcp is a Spreadsheets & Excel analysis skill for AI agents, published by witanlabs in the witan-cli repository on GitHub. Skillspace rates witan-xlsx-mcp C (79/100) and it passed the safety scan; the rating is based on static analysis only.

Read, explore, understand, create, and modify Excel workbooks (.xls, .xlsx, .xlsm). You cannot read Excel files with cat, head, or normal file-reading tools — running JavaScript against the workbook via the Witan MCP server's `xlsx_exec` tool is the only way to open or inspect them. Trigger when you or the user need to open or look inside a workbook, find its sheets or where data lives, read cells/rows/columns/ranges, search for values or labels, trace how a figure is calculated, or run what-if scenarios; and equally when asked to create a new workbook or financial model from scratch, add or edit formulas, charts, formatting, tables, or data validation, or change an existing model without breaking its formulas or references. Trigger whenever a spreadsheet is referenced by name or path — even casually ('check report.xlsx', 'build me a model') — and when you need to inspect a workbook as part of a larger task.
