What is the .FSX File Extension?


.FSX File Extension Description:

The FSX file extension is associated with the Lotus 1-2-3 program developed by Lotus Software, and which was later bought by IBM. Lotus 1-2-3 is a spreadsheet application that is part of the Lotus SmartSuite software, with the latest version being 9.8. Quite similar to its counterpart, Microsoft Excel, the Lotus 1-2-3 application may be used under the Microsoft Windows operating system.

The .fsx extension holds data keyed in by users utilizing the Lotus 1-2-3 application. Also, with the Microsoft Excel compatibility support embedded into it, the .fsx file format is capable of handling and storing data encoded in the spreadsheet of Excel.

When users save their projects in Lotus 1-2-3, the program will automatically create the file with an .fsx file extension. It will, then, archive all the data inputted into the rows and columns of the spreadsheet. Also, the formatting and settings will also be saved into the .fsx extension, and can be later applied when the said file is opened.

Note, however, that the .fsx extension can only be opened using Lotus 1-2-3, and will return an error if Microsoft Excel is used.

The latest version of Lotus 1-2-3 incorporates the following features as add-ons to its basic functions:

* Web tables can now be easily integrated into the spreadsheet application with the HTML 3.2 support of Lotus 1-2-3.

* The HTML support of the program allows users to open and convert spreadsheet ranges to HTML documents, without the need for manual conversion. Also, conversions to HTML will not affect the text format, cell data, number format, and so on.

* Have additional support features that will allow the program to create spreadsheets (along with formats, templates, and dates) to be used in Microsoft Excel. The support can also read and write spreadsheets made using the said program.
