Use this skill when a PPTX file needs to be rendered, inspected, created, or modified through Witan PPTX. The tool runs sandboxed Office.js-compatible JavaScript plus Witan PPTX chart extensions against PPTX files via `witan pptx exec`.
Read, explore, create, and modify Google Sheets spreadsheets via the witan CLI. You cannot read a Google Sheet with normal file tools — running JavaScript against it via `witan gsheets exec` is the only way to open or inspect it. Trigger whenever a Google Sheet is referenced — a `gs://SPREADSHEET_ID` ref, a `https://docs.google.com/spreadsheets/d/...` URL, or a request to read/build/edit a sheet 'in Google Sheets'/'on Drive'. Also trigger when a `gsheets` command fails with an authorization error so you can run the connect/authorize flow. For Excel files (.xlsx/.xls/.xlsm) on disk, use the witan-xlsx skill instead — the in-sheet JavaScript API is identical, only the access flow differs.
Only for agents running inside ChatGPT; all other agents use witan-xlsx-mcp instead. 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.

Extract text from source documents (PDF, DOCX, PPTX, HTML, Markdown) for spreadsheet workflows. Use to understand source material before populating workbooks.
