A spreadsheet plugin for MulmoChat - a multi-modal voice chat application with OpenAI's GPT-4 Realtime API.

This plugin provides a full-featured spreadsheet component with:

• Excel-like cell editing with formula support
• Mathematical functions (SUM, AVERAGE, MIN, MAX, etc.)
• Text functions (CONCATENATE, LEFT, RIGHT, MID, etc.)
• Date functions (TODAY, NOW, DATE, YEAR, MONTH, DAY, etc.)
• Logical functions (IF, AND, OR, NOT, etc.)
• Lookup functions (VLOOKUP, HLOOKUP, INDEX, MATCH)
• Financial functions (PMT, PV, FV, NPV, IRR)
• Multi-sheet support
• Excel file import/export (.xlsx)
• Cell formatting and styling

Note: This package uses SheetJS for Excel file import/export. SheetJS is not installed from npm, but directly from the official SheetJS CDN:

https://cdn.sheetjs.com/xlsx-0.20.3/xlsx-0.20.3.tgz

See SheetJS Installation Guide for details.
