Excel converting columns to rows

I have a large Excel sheet (approx 150 columns x 7000 rows and growing every day) but need to extract information in a better way. I don't have access to database software, only Excel. I've managed to get the result I want using normal Formulas, but the file size is almost 100mB (up from 4mB originally) and not workable - it's just too slow. I created a pivot table that only partially solves the problem. I'm new to VBA, so I tried a few examples on here to try to learn but most are too complex for me at the moment. In theory, "Convert row with columns of data into column with multiple rows in Excel" looks to partially resolve my problem, but I just can't get it to run! While I can see the code in the module, it does not appear in the macro list when I press the run button. Here is what I'm starting with-

Name1   Name2   Location    Subject1    Subject2    Subject3
Fred    Jones   England     Spanish     Maths       English
Peter   Brown   Germany     English     (empty)     Maths
Erik    Strong  Sweden      Chemistry   English     Biology

Required result -

Name1   Name2   Location    No.         Type    
Fred    Jones   England     Subject1    Spanish 
Fred    Jones   England     Subject2    Maths   
Fred    Jones   England     Subject3    English 
Peter   Brown   Germany     Subject1    English 
Peter   Brown   Germany     Subject3    Maths   
Erik    Strong  Sweden      Subject1    Chemistry   
Erik    Strong  Sweden      Subject2    English 
Erik    Strong  Sweden      Subject3    Biology 

Can anyone help please? Thank you!

I want to share a script I use regularly. Use it when you have multiple transactions, events, etc. on a single row when you want every transaction, event, etc. on a separate row. It takes columns that contain the same data type (ex. Subject1, Subject2, Subject3...) and need to be combined into one column (ex. Subject) across multiple rows.

In other words, your data that looks like this:

Name   Location   Subject1   Subject2   Subject3

Will look like this:

Name   Location   Subject1
Name   Location   Subject2
Name   Location   Subject3

This script assumes that your fixed column(s) are on the left and the columns to be combined (and split out into multiple rows) follow on the right. I hope this helps!

You can use the transpose function, both with and without VBA. Here's a code I just threw together:

Sub test()
lastRow = ActiveSheet.Range("A" & Rows.Count).End(xlUp).Row
lastColumn = ActiveSheet.Range("A1").SpecialCells(xlCellTypeLastCell).Column
Dim rng As Range
With Sheets("Sheet2")                   ' the destination sheet
Set rng = .Range(.Cells(1, 1), .Cells(lastColumn, lastRow))
End With
rng.Value = _
Application.Transpose(ActiveSheet.Range(Cells(1, 1), Cells(lastRow, lastColumn)))
End Sub
