VBA: How to Insert Rows Based on Cell Values Without Overwriting Existing Data?
I'm learning this framework and I've tried everything I can think of but Hey everyone, I'm running into an issue that's driving me crazy... I've been struggling with this for a few days now and could really use some help. I'm trying to automate a process in Excel using VBA where I need to insert new rows based on specific cell values in a certain column. For example, if the value in column A is 'Insert', I want to insert a new row above that cell but I run into issues when there are multiple instances of 'Insert' or when the sheet already has a lot of data. It often leads to overwriting existing data or inserting rows in the wrong place. I attempted to loop through the rows and check for the condition, but it seems to mess up the row index as I insert new rows. Here is the code I have so far: ```vba Sub InsertRowsBasedOnCellValue() Dim ws As Worksheet Set ws = ThisWorkbook.Sheets("Sheet1") Dim lastRow As Long lastRow = ws.Cells(ws.Rows.Count, "A").End(xlUp).Row For i = lastRow To 1 Step -1 If ws.Cells(i, 1).Value = "Insert" Then ws.Rows(i).Insert Shift:=xlDown, CopyOrigin:=xlFormatFromLeftOrAbove End If Next i End Sub ``` When I run this code, it gives me a runtime behavior 1004: "Application-defined or object-defined behavior". I suspect it might be related to how I'm managing the row indices as I insert rows. I've also tried adjusting the loop direction (from top to bottom) but it just causes rows to be skipped. I would appreciate any advice on how to manage inserting rows correctly while considering the existing data and avoiding overwrites. Also, if there are best practices for handling large datasets in VBA, I am keen to learn those as well. Am I missing something obvious? What am I doing wrong? Has anyone dealt with something similar? I appreciate any insights!
