SUMMARY

What it does

This Agent Skill enables an agent to create, edit, analyze, or convert Excel spreadsheet files (.xlsx, .xlsm, .xltx) where the workbook file is the primary deliverable. It covers formulas, formatting, financial models, multi-sheet workbooks, and tabular cleanup exported to Excel. It also applies to .csv/.tsv when spreadsheet output is desired. The skill is not intended for Word documents, HTML reports, standalone Python scripts, database pipelines, or Google Sheets API work. Evidence from the source inspection indicates the skill provides detailed guidance on using openpyxl, pandas, and markitdown, with mandatory recalculation via LibreOffice to ensure formulas evaluate correctly. It includes specific instructions for financial model formatting, formula compatibility, and handling of openpyxl gotchas. The skill is adapted from an Anthropic skill and is vendored in the K-Dense-AI/scientific-agent-skills repository.
