Examples of VBA InStr
Visual Basic for Applications (VBA) InStr function is a very useful tool in finance when it comes to dealing with data manipulation especially in Excel. Here are three real-world examples where it comes in handy:
Searching Transaction IDs or Product Codes: If you are working in the finance department of an e-commerce company, you get several lines of transaction data every day. Say, you want to identify a specific series or type of product codes or transaction IDs from this large data set. With the InStr function, you can easily identify and extract the desired information. For instance, if product codes starting with the letter ‘X’ signify kitchen appliances, InStr can help you quickly find all such transactions.
Email Audit: If you work as an audit professional, you may be required to review a large number of emails containing specific finance related keywords. Using the VBA InStr function, you can quickly write a script to identify emails containing specific keyword(s), saving you a significant amount of work and time.
