Mesa currently allows import from 1-2-3 files and from Excel files.

It's easy to open an Excel file. Just use the Workbook->Open menu command, and the browser will show you .xls and .xlw files (as well as .mesa files).

Mesa and Excel are not 100% compatible. Most Excel files will open in Mesa satisfactorily, in terms of bringing in all text, data, formulas, range labels and formatting.

Charts, macros, text boxes etc are not imported in this version of Mesa. In some cases Excel has features which Mesa doesn't yet have (for example pivot tables, ODBC database access, and some advanced functions (eg @RANK) and these can't be imported either. In future releases we intend to enhance the Excel compatibility.
