MiniMax-AI/minimax-xlsx
Create, read, analyze, and validate Excel/spreadsheet files
by minimax-aiFree
Description
Minimax-xlsx is an agent skill for creating, reading, analyzing and validating Excel and CSV files. It handles .xlsx, .xlsm, .csv and .tsv files, and it works by editing the underlying XML directly rather than round-tripping the file through a library. The skill says this matters because library round-trips can corrupt VBA macros, pivot tables and sparklines, while direct editing keeps existing formatting and features intact. It covers reading a workbook, building a new one from scratch, editing an existing file without losing its format, repairing formulas, and validating the result. It also applies financial formatting conventions, including formula-based calculations and color-coded cell roles. Typical tasks are extracting summary statistics from a multi-sheet workbook into a report, building a financial model with SUM formulas and accounting-style borders, adding a percentage column to a budget without touching the other data, fixing broken cross-sheet references in an inherited file, and checking that calculated cells use formulas rather than hardcoded values. The skill is published by MiniMax on officialskills.sh.…
