How to open UDF files
Did your computer fail to open an UDF file? We explain what UDF files are and recommend software that we know can open or convert your files.
What is an UDF file?
We know of 3 different uses of the UDF file type, one of them being User Defined Function for Excel. Read the details below.
The UDF file extension indicates to your device which app can open the file. However, different apps may use the same file extension for different types of data. So an UDF opener may not be able to open all kinds of UDF files. In this case, look through all formats to make sure you find the best suited UDF viewer.
User Defined Function for Excel
Also known as user-defined function files, these UDF files are generated by Microsoft Excel when users create custom formulas for their spreadsheet documents. Microsoft Excel provides VBA (Visual Basic for Applications) support. This allows users to develop custom functions and formulas for their spreadsheets.
Users can access previously saved formulas and functions through these UDF files to use them across multiple spreadsheets without the need to code the functions and formulas again manually. The content of a .udf file is used by Microsoft Excel whenever a user opens and edits a spreadsheet with custom functions and formulas that have been saved in the UDF file. The data in a .udf file is also updated by Microsoft Excel when the user changes the saved formulas and functions of the spreadsheet.
