Convert 123 to XLSX

Understanding 123 and XLSX file formats

The 123 file format is associated with Lotus 1-2-3, a spreadsheet program that was popular in the 1980s and 1990s. It was one of the first spreadsheet applications available for personal computers and was widely used for data analysis and financial modeling. The 123 format is now considered obsolete, as Lotus 1-2-3 has been discontinued.

On the other hand, the XLSX file format is a modern spreadsheet format used by Microsoft Excel, part of the Microsoft Office suite. Introduced with Excel 2007, XLSX is based on the Open XML format, which allows for more efficient data storage and better compatibility with other software. It is the standard format for Excel spreadsheets today.

How to convert 123 to XLSX

Converting a 123 file to an XLSX file involves opening the 123 file in a compatible program and saving it in the XLSX format. Since Lotus 1-2-3 is no longer supported, you may need to use alternative software that can handle 123 files.
