The .123 file extension symbolizes the Lotus 1-2-3 spreadsheet application originally released in January 1983 by Lotus Software, now an IBM company. It was the first true electronic spreadsheet for IBM PC compatible computers.
Overview and Features
Lotus 1-2-3 was used to analyze and calculate financial data and statistics, allowing users to work with numbers, analyze trends, chart results, and share their findings with others. This software played a major role in creating the original set of standards for electronic spreadsheets. Prior to its release, most spreadsheets relied upon punch cards or dedicated terminals for their use.
The .123 file format is based on formulaic cells referred to as Workbooks characterized by box borders enclosing data fields organized into vertical columns referred to as Streams and numerical calculations grouped as rows called Streams Indexes. The initial organized layout of well-defined streams and indexes allowed Lotus 1-2-3 to process complex calculations quickly on personal computers—faster than any methods used previously.
Creating & Saving Files in the.123 Extension
Lotus 1-2-3 could save data in a variety of file formats labeled using classical extensions such as .WKS, .WK1, .WK2, .WK3, .WK4, .WQ1 and .123. The latter could contain formatted spreadsheets up to Release 2.01 but not support macro instructions, while the former supported the instruction technology.
The Lotus 1-2-3 full program was initially sold on diskettes; as such customers had the option of saving their work on floppy disks using one of the earlier versions of the software. With today’s version known as Freelance Graphics 2.1, you are able to save your .123 files to a diskette, or additionally can export the files in other popular formats: Excel ( .XLSX, .XLSM) SpreadsheetML ( .XML) Lotus WordPro ( .LWP) Text ( .TXT) Syllable Spreadsheet ( .SOL) File Interchange Format (

After installing the required software, the operating system will usually automatically associate an unknown file type (in this case .123) with the new application. If this does not happen, we can help the system a bit by selecting the software for it, which it should always use to open files with the .123 extension.
When choosing the software we can select the system to use this software every time.
Remember!
Using it for the first time it is good to check whether the .123 file opened in the application can be read by us and opens in a way that allows us to use it. If everything is in order, select this option the next time you open a file with the .123 extension. However, if the file has not opened correctly, we have to look for a different software, with which we can open files with the .123 extension. Select a different software from our list and install it on your computer. After the software is installed, repeat inspection openings of a .123 file. Sometimes you have to repeat the operation several times.
Other instructions
If none of the programs listed by us to work with the .123 file has not meet your expectations, you can try searching other websites. But remember to avoid downloading programs "that can open any file". These applications not only have very limited functionality, but may also expose you to expense tens of dollars when purchasing a license.
In the vast majority of cases you will find the program dedicated to support the .123 file, or any other file format. In addition, there is a chance that it will be a free program, and its functionality (concerning the .123 file) will be extended to the maximum.
It is also good to check
- if the .123 file has no errors
- or if it has been copied (or downloaded by the browser) thoroughly
