The free version of Easy-XL contains all of the commands in the Workbook section of the Ribbon. Both versions support Extensions. Additionally, the free version also supports double-clicking on a column name in row 1 to sort a worksheet.
The trial version of Easy-XL reverts to the free version after 30 days. The Worksheet, Rows, Columns and Cells sections of the Ribbon are then hidden.
The free version can be updated to the full version at any time by using the Register option in Easy-XL's help menu.
When you purchase the full version, your license allows you to install the software on all of your work and personal computers.
