This Skill helps you create, edit, validate, and repair spreadsheet files without breaking formulas, formatting, or workbook structure. It is designed for situations where the spreadsheet itself is the deliverable and correctness matters more than quick ad hoc edits.
Use the xlsx skill to inspect the attached spreadsheet, repair any workbook issues, and return a corrected file with formulas recalculated.

To edit an Excel file without breaking formulas, use a validation and recalculation process that checks Office XML structure and preserves workbook integrity. This approach safely updates .xlsx files while maintaining original conventions and formula correctness.
The best way to validate a corrupted Excel workbook is to inspect its XML structure, relationships, content types, and namespaces. This process detects schema-related issues and repairs common problems like invalid durable IDs to restore file integrity.
You can recalculate spreadsheet formulas using LibreOffice-based recalculation to identify formula errors before delivery. This ensures the returned workbook contains no calculation errors and maintains structural correctness for end users.
While openpyxl handles basic workbook manipulation, comprehensive Office XML schema and relationship checking requires additional validation logic. This validates content types, IDs, and namespaces to prevent file corruption beyond standard openpyxl capabilities.
Yes, you can create new .xlsx, .xlsm, .xltx, .csv, and .tsv deliverables with formulas and formatting intact. The process builds structured spreadsheets where the file itself is the deliverable and correctness is prioritized.
Spreadsheet formula errors after editing often occur due to broken XML relationships or whitespace preservation issues. Validating workbook integrity and applying LibreOffice-based recalculation detects and fixes these structural problems safely.
