You must understand how to use loops effectively in Excel and VBA to get the most out of them.
Loops in VBA allow you to go through a set of objects/values one by one and analyse them. For each loop, you can also conduct particular activities.
Here's a quick example of how to use VBA loops in Excel.
In practise, VBA loops in Excel can help you automate activities in a variety of ways.
Here are a few additional examples of how VBA loops can be helpful:
Iterating over a set of cells and inspecting each one (highlight cells with a specific text in it).
Looping through all of the worksheets and doing something with each one (for example, protecting or unprotecting it).
Go through all of the open workbooks in a loop (and save each workbook or close all except the active workbook).
Iterate over all of the characters in a cell (and extract the numeric part from a string).
All the values in an array are looped through.
Iterate across all of the charts/objects (and give a border or change the background color).
