UDFs are helpful for customized calculations or when normal Excel features are inadequate.

Step 6: Error Dealing with

In VBA, error dealing with is essential for creating sturdy code. Errors might come up from invalid information inputs, incorrect information ranges, or surprising values. VBA offers a way to deal with errors utilizing the On Error assertion.

Right here’s an instance:

Sub ErrorExample()
