What is 123 file?

The .123 file extension is created by a program launched by IBM as part of its Lotus SmartSuite. It is a file containing data being organized into rows and columns with the option of functions being applied to cells. These functions allow for data analysis techniques to be performed onto the cells. The 123 format is a representation of the features of the Lotus spreadsheet, the first being the spreadsheet function itself, the second as a medium of creating charts and the third being database operations.

What else may cause problems?

There can be more reasons which determine that you are not able to open the 123 file (apart from the lack of the proper application installed).

First - the 123 file may be incorrectly associated with the application installed to support it. In this case, you need to change this association by yourself. To do this, right-click on the 123 file that you want to edit, click "Open with" and then select the program from the list that you have installed. After this operation, the problems with opening the 123 file should be solved.

Second - the file you want to open can simply be damaged. Then, the best solution is to find a new version of given file, or download it again from the same source as before (maybe for some reason in the previous session the download of the 123 file has not been completed and it cannot be opened properly).
