Comparing two unsorted excel columns

[ProTester]

Hi everyone,

I have a script that compares two unsorted columns (in 2 differtent sheets) using .match.
If match gives me the row number then I check if columns are equal.

Is there a faster way?

Number of rows could be 20'000 to 200'000


Code:

Code:

For i = 1 To rowCount1 Step 1
   
    x = objXL.Application.Match(objMyWorksheet1.Cells(i,1).value, objXL.Sheets(sheet2)Range("A1:A"&rowCount2),0)
     If not isNumeric(x) then
     objMyWorksheet1.Cells(i,1).Interior.ColorIndex = 6
  

     Else

    
      For z = 2 To columnCount1 Step 1
      rowA= trim(objMyWorksheet1.Cells(i,z).value)
      rowB= trim(objMyWorksheet2.Cells(x,z).value)
       If isnumeric(rowA) then rowA= Cdbl(rowA)
       If isnumeric(rowB) then rowB= Cdbl(rowB)
    
    
       If rowA <> rowBThen Call CheckRow(objMyWorksheet1,objMyWorksheet2,i,x,z)
    
      Set rowA= nothing
      Set rowB= nothing
     next
  End if
  
  next

CheckRow(objMyWorksheet1,objMyWorksheet2,i,x,z) is required because I need to see if there are some specific values that I have to ignore.
I'd like to speed up this part (and if exists, to use a faster way than match)



Code:

Code:

For z = 2 To columnCount1 Step 1
      rowA= trim(objMyWorksheet1.Cells(i,z).value)
      rowB= trim(objMyWorksheet2.Cells(x,z).value)
       If isnumeric(rowA) then rowA= Cdbl(rowA)
       If isnumeric(rowB) then rowB= Cdbl(rowB)
    
    
       If rowA <> rowBThen Call CheckRow(objMyWorksheet1,objMyWorksheet2,i,x,z)

Thank you

Thanks for keeping the forum clean and posting in the right section.

Can you illustrate with the help of an example data what you are trying to achieve? 

I didn't really get this -

If match gives me the row number then I check if columns are equal.

Hi,

I've loaded two Attachments.

for every key in KEY_Column.
If key in SHEET A exists in SHEET B then check the entire row.

Code:

x = objXL.Application.Match(objMyWorksheet1.Cells(i,1).value, objXL.Sheets(sheet2)Range("A1:A"&rowCount2),0)

this code let me get the row number of the found key in SHEET B.
If I find a match then I check Attribute One, Two, Three, Four, etc... with this code:

Code:

For z = 2 To columnCount1 Step 1
      rowA= trim(objMyWorksheet1.Cells(i,z).value)
      rowB= trim(objMyWorksheet2.Cells(x,z).value)
       If isnumeric(rowA) then rowA= Cdbl(rowA)
       If isnumeric(rowB) then rowB= Cdbl(rowB)
    
    
       If rowA <> rowBThen Call CheckRow(objMyWorksheet1,objMyWorksheet2,i,x,z)

What I am asking if there is a faster way to do the Attributes check rather than a For cycle.

Sorry, english is not my language.

I hope I cleared my issue.
Thank you
