Mastering Row Deletion in Excel VBA: Deleting Rows Based on a Condition

Excel is a powerful tool, and when combined with VBA (Visual Basic for Applications), you can automate tasks to save time and improve efficiency. One such task that many users face is the need to delete entire rows based on specific conditions. In this post, we’ll explore how to delete rows in Excel VBA when the value in a certain column meets a particular criterion – in this case, when column F contains the letter "T".

The Problem: Why Rows Aren't Deleted Completely

In an existing macro, a user attempted to delete rows from Sheet1 where column F equals "T". Here's the code they used:

Although this code successfully deleted some rows, it failed to remove all desired rows. The reason? As rows are deleted, the indices of the remaining rows change, causing the loop to skip over certain rows immediately following deleted ones. This is a common pitfall in row deletion.

The Solution: Looping Backwards

To tackle the issue of skipped rows, a better approach is to loop through the rows in reverse order. This way, when a row is deleted, the next row to be checked is unaffected in terms of its position. Below is the revised code that ensures all relevant rows are deleted:

Breakdown of the Solution

Looping Backwards:

The modified loop starts from the last row (lRow) and moves to the second row (i.e., For i = lRow To 2 Step -1). This ensures that when a row is deleted, the loop continues correctly through the remaining rows.

Condition Check:

The condition If InStr(.Range("F" & i), "T") > 0 checks if the value of the cell in column F contains "T". If it does, the entire row is deleted.

Updating Screen:

The Application.ScreenUpdating = True at the end of the subroutine allows Excel to refresh the display, ensuring that the deletions are visible.

Conclusion

By using a backward loop in your Excel VBA code, you can effectively delete rows based on specific cell conditions without losing track of your position among remaining rows. This technique not only saves time but also enhances code reliability. Give this approach a try in your own Excel projects, and you'll find it easier to manage data efficiently.

Now that you know how to delete rows based on a condition in Excel VBA, you can streamline your data handling and improve your overall productivity in Excel. Happy coding!
