Example session with this skill installed
I have a monthly_report.xlsx with complex merged headers and print areas. Please update the data in 'Sales Data' sheet from the attached CSV, keeping all formatting identical.
- Read your context and instructions
- Compiled the excel format fidelity
I have updated the 'Sales Data' sheet in monthly_report.xlsx by copying the original file and modifying cell values to ensure 100% format fidelity.
Excel Processing Log

Format Verification Results
The file was verified across 6 key metrics. All discrepancies were resolved:
- Print Setup: Identical to source.
- Merged Cells: All 12 ranges preserved.
- Cell Fills/Fonts: Theme colors and font sizes (Gulim 9pt) confirmed.
- Row/Column Specs: Manual heights and widths remain unchanged.
Next steps

About this skill
Ever asked an AI to "just change one number" in your Excel report — and gotten back a file with broken merges, missing print areas, and the wrong font? That happens because AI rebuilds your spreadsheet instead of editing it. This skill fixes the problem at the root.
What it does
🛡️ Copy, don't re-create. Enforces work paths that structurally preserve formatting — file copy for value edits, in-place sheet cloning for new monthly tabs, component-level style transfer only as a last resort. 🔍 Machine-verified delivery. Every output is fingerprint-diffed against the original across 6 dimensions: print area & page setup, merged cells, fill colors, row heights & column widths, fonts, and cell formatting (number format, borders, alignment). Zero unintended diffs, or it doesn't ship. ⚠️ Trap detection built in. One command (--inspect) flags elements openpyxl silently destroys — charts, images, VBA macros, pivot tables — before work starts, so you're never surprised. 📋 Battle-tested pitfall list. Encodes hard-won lessons: cross-workbook _style corruption, merge-then-style ordering, default-font (Normal style) mismatches, theme color quirks, LibreOffice number-format mangling.
How to use it: Drop the folder into your skills directory. It triggers automatically whenever an existing .xlsx/.xlsm is the input — no need to say "keep the formatting." Includes two ready-to-run scripts: verify_format.py (diff & inspect) and clone_format.py (full-fidelity sheet cloning, including page setup).
Who it's for: Anyone whose Excel files are documents — printed reports, official forms, monthly templates — where a shifted border or lost merge isn't cosmetic, it's a redo.
