Use Caution when Saving Excel Files!
Use the File | Save To Multi-Sheet Excel File command to save multiple worksheets in a single Excel document. Note that this command only saves Excel files in the XLSX format.
A file can be saved in an Excel format from Grapher worksheet, but only one worksheet can be saved when using the File | Save or File | Save As command. If a multi-worksheet Excel file is opened and saved as an .XLS or .XLSX file from the Grapher worksheet, be aware that only the single worksheet is saved in the document. If the existing file is overwritten, all the unused worksheets are destroyed. In this case, a warning message is issued. The message reads: Saving this worksheet will destroy all but one of the sheets in the existing *.xls, *.xlsx file. To overwrite the file, click OK. To choose a different file name, click Cancel.
