About xlsx

xlsx
Creates, edits, analyzes, or converts Excel spreadsheets
xlsx is an agent skill for creating, editing, analysing and converting Excel spreadsheets, in .xlsx, .xlsm and .xltx formats, where the workbook file is the main deliverable. It covers writing formulas and formatting with openpyxl, bulk data in and out with pandas, a quick look at a sheet, and reading a model that has both formulas and values. The skill does not assume that packages are installed. It advises reusing a suitable environment, or running with uv and a pinned openpyxl version. Optional tabular readers should be installed only when needed, and MarkItDown needs its spreadsheet extra. The bundled workflow was exercised with openpyxl 3.1.5 and LibreOffice 26.2.4.2, and the skill notes that current online LibreOffice help describes a later version. Use it when a spreadsheet is the thing you need to produce or change, such as a model with live formulas or a formatted report. For text documents, a different skill applies. It is part of the k-dense-ai scientific agent skills repository on GitHub, which has about 49,600 stars. The listing shows it as free, and it has about 1,800 installs.
