PancakeSpreadsheet

Grasshopper plugin for reading/writing xls(x) files without Excel, based on NPOI.

This is more stable and reliable than the COM approach and is cross-platform.

Future plan

• Provides access to Google Spreadsheet, Airtable, etc. It can be done by implementing custom classes with NPOI interface IWorkbook to provide a unified access approach.
