Document to Excel (XLSX)
The Document to Excel (XLSX) utility extracts tabular data, financial figures, and structured lists from Markdown, CSV, and text documents into formatted Microsoft Excel (.xlsx) workbooks. It auto-detects numerical formats, dates, and currency values.
Operating entirely client-side, the spreadsheet engine compiles multi-sheet workbooks with column auto-sizing and styled headers in local browser memory. Financial models, customer data, and proprietary pricing sheets remain 100% private.
