Microsoft Excel takes precedence in any discussion of XLS1 files. Although not a standard Excel file format like .xlsx or .xls, some instances may require Excel to open an XLS1 file. When faced with such a situation, proceed as follows:

Open Microsoft Excel. You can download it from here if you haven't installed it yet.
Click on 'File' and then 'Open'.
Navigate to the location of your XLS1 file and select it.

If your XLS1 file is a renamed Excel file, it should open successfully. However, if the file was not initially created in Excel, you may encounter errors or garbled data. It is always best to ensure you are accessing the file in the intended application.

Other Uses of XLS1 Extension

Besides Microsoft Excel, other applications or systems may use the XLS1 extension. Since this file extension is not common, you might need tailored software or utilities to open and interpret such files. In some scenarios, programming languages like Python or R can be used to open and process these files, especially if they contain tabular data.

The OpenPyXL library in Python, for example, is a handy tool for reading and writing Excel 2010 xlsx/xlsm/xltx/xltm files. Similarly, the readxl package in R provides functions to read Excel files into R. Note that using these tools requires a good grasp of the respective programming languages.
