What is 123 file?

The file with the extension 123 is the Spreadsheet Files file type. It was designed by IBM. In addition to this file, the Spreadsheet Files category includes 100 related files. Lotus 1-2-3 Spreadsheet is supported by 4 operating systems. These systems consist of , Linux, Mac OS, Windows, although it may occasionally be found on another system, it will be non-functional. It is recommended to use NeoOffice to handle this file. This is a program created by Planamesa Inc.. Alternatively, you can use 9 other programs. Apache OpenOffice, WordPerfect Office, Gnumeric, Lotus 1-2-3 will apply when it is not possible to use NeoOffice.

How to open 123 file?

The main problem with Lotus 1-2-3 Spreadsheet is that the 123 file is incorrectly associated with programs. This causes the file 123 to open by system applications not designed for this purpose, or to display a message that there is no associated program. This problem can be easily remedied.

The first thing you should do is just "doubleclick" on the 123 file icon you want to open. If the operating system has an appropriate application to support it and there is also an association between the file and the program, the file should be opened.

Step 1. Install NeoOffice

The first step is to check if the computer has the NeoOffice program installed. To do this, enter the name NeoOffice into the system search engine. If it is not, installation may solve the problem, as most applications create file associations during installation. Later in this article you will find a list of programs that can open 123 files.

Step 2. Create association of NeoOffice with 123 files

If, despite the installed application, the 123 file does not start in the NeoOffice application, you must create a file association. It is most convenient to call the context menu with the right mouse button and select Properties. The window will show, among other things, the type of the file and the information by which the program is used to launch the file. Using the "Change" button we can select the desired program. If there is no software on the list, simply select "Browse" and manually select the directory where the application is installed. Checking the "Always use the selected program ..." box will permanently associate the 123 file with the NeoOffice program.

Step 3. Update NeoOffice to the latest version

If, despite the association of the NeoOffice program with the Lotus 1-2-3 Spreadsheet file, the file still does not open, check the program version and possibly update it to the newest version. This can be done using the application (if it provides such options) or from the Planamesa Inc. website and install the latest version.

Step 4. Check for the following problems with the 123 file

The problem may also be with the file itself if the above steps don't work. This could be due to the file itself, the cleanest issues are:

Very often, the file may be size 0 or incomplete. This suggests truncating the 123 file contents when downloading or copying. Downloading the file again should fix the problem.
The operating system may be infected with a computer virus. A virus scan using an up-to-date antivirus program should fix the problem. If this is not possible, you can use the online scanner. For the best results, we will scan the entire operating system, not just our 123 file. As a result of the scan, sometimes it is not possible to recover 123 files, which are deleted if there is a backup of this file, then after restoring it, it must also be scanned.
A typical compatibility error - the program does not support the older version of the 123 file. These problems are known and are often very easy to fix using the software developers's website.
There can be many reasons for this. Depending on the type of file, it is necessary to repair it accordingly. Some programs offer the option of recovering data from damaged 123 files. You can restore the file from a backup or use IBM help.
When reading, a message appears that the file was encrypted or corrupted. The encrypted file 123 except for the special designation, works normally, but only on the device where it was encrypted, before transferring it to another machine, decryption is required.
The operating system protects files in some locations (e.g. the root of the system partition) against unauthorized access. While there is usually no problem reading such a file, it may not be possible to save it. It is best to move 123 to a different directory.
This problem only occurs with more complex files. Some file types can only be opened in one program at a time. Just close unnecessary programs. Sometimes you have to wait for the session to the file 123 to close. Some anti-virus or backup software may occupy the 123 file for a certain period of time. If nothing helps, please reset the device.
