Excel XLSX

Use this skill when the user asks for an Excel spreadsheet or editable table.

Output

Create a real .xlsx file, not plain text renamed as .xlsx.
Save it under the current workspace, preferably workspace/, vault/, or the current conversation folder.
Use a clear filename ending in .xlsx.
Reply with the file path and a short note about what was created.

Tool

python3 scripts/create_xlsx.py \
  --title "Sheet title" \
  --input data.csv \
  --output output.xlsx

You can also pass data directly:

python3 scripts/create_xlsx.py \
  --title "Cotizacion" \
  --data "Item,Cantidad,Precio\nSilla,4,120000\nMesa,1,450000" \
  --output cotizacion.xlsx

Input Formats

CSV or TSV files.
Markdown tables.
JSON array of objects or array of arrays.
Plain text tables separated by commas, tabs, semicolons, or pipes.

Guidance

Put headers in the first row when the user gives categories or columns.
For budgets, quotes, inventories, grades, schedules, or reports, include totals and clear column names when useful.
Use formulas only when the user needs calculations and the formula is straightforward.
If the user gives messy text, normalize it into a clean table instead of blocking.
