123 File

File extension .123
CategoryDocument File
Description123 Lotus is a file format used by the Lotus 1-2-3 spreadsheet program, which was popular in the 1980s and 1990s. The 123 Lotus format is used for storing data in a tabular format, allowing users to easily organize and manipulate large sets of data.

The 123 Lotus format is based on a system of worksheets, which consist of rows and columns that can be used to store and manipulate data. The format includes features such as formulas, macros, and charts, which allow users to perform complex calculations and generate graphical representations of their data.

Although the Lotus 1-2-3 program is no longer as widely used as it once was, the 123 Lotus format remains a common file format for older spreadsheets and datasets. While newer spreadsheet programs such as Microsoft Excel have largely supplanted Lotus 1-2-3, many users still maintain legacy datasets in the 123 Lotus format and may need to convert these files to more modern formats in order to use them with newer software.

In summary, 123 Lotus is a file format used by the Lotus 1-2-3 spreadsheet program for storing data in a tabular format. While the program is no longer widely used, the 123 Lotus format remains a common file format for older datasets and may require conversion for use with modern software.

FAQ ▼

What is a .123 file?

A .123 file is a spreadsheet created with Lotus 1-2-3, an early spreadsheet program developed by Lotus Software. It was popular in the 80s and 90s before Excel became the industry standard.

Why convert 123 to XLSX?

XLSX is the modern Microsoft Excel format that supports advanced features, wide compatibility, and ongoing support. Converting 123 to XLSX ensures your legacy spreadsheets remain accessible and editable.

Will my data and formulas be preserved?

Yes. The converter retains data, cell structure, and most standard formulas. Some legacy functions might need review, especially if they are outdated or unsupported in Excel.

Can I open 123 files directly in Excel?

Most modern versions of Excel no longer support .123 files directly. Converting them to XLSX ensures compatibility without needing Lotus 1-2-3 or older Excel versions.

Can I convert multiple 123 files at once?

The online tool supports one file at a time. For batch conversion of many 123 files, we recommend using the desktop version of our converter.

Do I need Lotus 1-2-3 installed for conversion?

No. Our converter works independently and does not require any Lotus software installed on your system.

Is the conversion secure?

Yes. All uploaded files are processed securely and deleted automatically from our servers shortly after conversion to protect your data.
