What is a .123 file?

A .123 file is a type of spreadsheet file that was originally created by a program called Lotus 1-2-3. This type of file organizes data in a grid of rows and columns, making it useful for tasks like managing financial budgets or tracking quarterly earnings. The data in the cells of a .123 file can include numbers, text, or formulas. Formulas are special instructions that automatically calculate and display values based on the data in other cells, which is very helpful for tasks like summing totals or calculating averages.

Although Lotus 1-2-3, the original program that created .123 files, is no longer available, there are several other programs that can open and work with these files. These include: 1. **OpenOffice Calc** - A free and open-source office suite that includes a spreadsheet program capable of opening .123 files. 2. **Gnumeric** - Another free spreadsheet program that can handle .123 files. 3. **Corel Quattro Pro 2021** - A modern spreadsheet program that is part of the Corel WordPerfect Office suite. It can open and edit .123 files. 4. **Planamesa NeoOffice** - An office suite for Mac computers that includes spreadsheet capabilities and can open .123 files.

If you have a .123 file that you need to view or edit, you can use any of these programs to open it.
