Provide support to load Excel file sheet-by-sheet in Spreadsheet Component

Currently, when importing an Excel file into the Spreadsheet component, the entire workbook is processed and converted into a single JSON structure. While this ensures formula consistency and cross-sheet reference accuracy, it can lead to performance issues and increased memory usage for large files with many sheets.

We need to support for sheet-by-sheet loading, where only the initially selected sheet is loaded, and additional sheets are fetched from the server on demand when the user selects them. This approach would:

  • Improve performance and reduce initial load time.
  • Allow better memory management for large workbooks.
  • Preserve formatting and styles more efficiently.
  • Avoid unnecessary processing of unused sheets.

This feature is especially useful for workbooks with many sheets where users typically interact with one sheet at a time.
