The skill document

ClawSheet Wizard

Excel-værktøj baseret på velafprøvede mønstre (pandas, openpyxl), forbedret med unikke features:

🆕 Unikke features (findes ikke i originalen)

Feature 1: Formel-tjekker & auto-retter

Scanner hele workbook'en for #REF!, #DIV/0!, #VALUE!, #NAME?, cirkulære referencer og forskudte formel-områder — og foreslår/udfører rettelser:

python3 scripts/formula_checker.py bog.xlsx --fix --out bog-rettet.xlsx
python3 scripts/formula_checker.py bog.xlsx --report rapport.md

Feature 2: Data-kvalitetsrapport

Genererer en rapport over: duplikater, tomme celler, tekst-tallene, afkortede ID'er (>15 cifre), blandede typer og dato-fælder:

python3 scripts/data_quality.py kunder.xlsx --out kvalitet.md

Feature 3: Skabelon-diff

Compares an edited file with the original and shows exactly what changed (celler, formler, formatering, skjulte ark) — perfekt til audit:

python3 scripts/template_diff.py original.xlsx redigeret.xlsx

Standard-operationer (arvet + forbedret)

Vælg værktøj efter job

  • pandas — analyse, reshaping, CSV-lignende opgaver
  • openpyxl — formler, stilarter, kommentarer, merged cells, skabelon-bevarelse

Datoer er serienumre med arv

  • Excel bruger 1900-datessystemet med falsk skuddag; nogle bruger 1904
  • Tid er brøkdele af dage — formatering og konvertering begge vigtige

Hold beregninger i Excel

  • Write formulas into cells instead of hardcoded results
  • Check copied formulas for wrong ranges, sheets and off-by-one
  • Lever ALTID uden formel-fejl

Beskyt datatyper

  • Lange ID'er, telefonnumre, postnumre og foranstillede nuller = tekst
  • Excel afkorter numerisk præcision over 15 cifre
  • Blandede tekst-tal-kolonner kræver eksplicit håndtering

Bevar struktur

  • Eksisterende skabeloner vinder over generiske stilarter
  • Skjulte rækker/kolonner, navngivne områder og eksterne referencer påvirker output
  • Match stilarter for nye celler

Genberegn og gennemgå

  • openpyxl bevarer formler, men beregner dem IKKE — brug formula_checker.py
  • Visuel gennemgang hvis layout betyder noget

Almindelige fælder

  • Type-inference ved læsning kan ødelægge ID'er
  • Kolonne-indeksering varierer — off-by-one i formler
  • .xlsm kan indeholde makroer; .xls er et stramt legacy-format
  • Store filer: brug streaming/chunked reads
  • FILTER, XLOOKUP, SORT, SEQUENCE fejler i ældre visere

Use this skill any time a spreadsheet file is the primary input or output. This means any task where the user wants to: open, read, edit, or fix an existing .xlsx, .xlsm, .csv, or .tsv file (e.g., adding columns, computing formulas, formatting, charting, cleaning messy data); create a new spreadsheet from scratch or from other data sources; or convert between tabular file formats. Trigger especially when the user references a spreadsheet file by name or path and wants something done to it or produced from it. Also trigger for cleaning or restructuring messy tabular data files into proper spreadsheets.
