This Skill handles any user task where a spreadsheet file is the primary input or output: opening, reading, cleaning, editing, creating, converting, formatting, charting, and delivering .xlsx/.xlsm/.csv/.tsv files while ensuring spreadsheets are dynamic, well-formatted, and free of Excel formula errors.
Open 'downloads/sales.csv' and produce a validated, formula-driven workbook 'sales_cleaned.xlsx' with preserved templates, formulas (not hardcoded), and zero formula errors.

Yes, you can convert messy CSV exports into validated, formula-driven .xlsx workbooks. The process cleans malformed rows, separates assumptions, applies formatting, and ensures formulas are entered dynamically rather than hardcoded, delivering a fully recalculated financial model.
To clean spreadsheet data, you can use a restructuring process that detects misplaced headers, fixes malformed rows, and removes junk data. This reshapes tabular inputs into proper sheets while preserving existing formatting and templates.
Yes, openpyxl can preserve existing templates and formatting when reading and writing .xlsx and .xlsm files. This allows you to edit spreadsheets dynamically without losing the original template structure, number formats, or color-coding standards applied to the workbook.
LibreOffice recalculation validates Excel formulas by running a script that recalculates values headlessly, without needing Excel installed. This mechanism ensures formulas are entered correctly, computes the resulting values, and detects and reports any Excel formula errors for repair.
This approach supports .xlsx, .xlsm, .csv, and .tsv files for reading and writing. It handles converting between these tabular formats while preserving templates, applying formatting, and ensuring zero formula errors before delivering the final workbook.
Excel formula errors after conversion often occur when values are hardcoded or formulas are malformed. You can fix this by enforcing a formula-first workflow that detects and reports specific formula errors, then uses LibreOffice recalculation to validate workbook integrity and ensure zero errors.
