Hi everyone,

I really need to be able to read the data from three columns in one Excel Spreadsheet (c:\SpreadSheet_1.xls)

then create a New Spreadsheet (c:\SpreadSheet_2.xls) on the fly.

Then write the Spreadsheet 1 queried data ("select Row,Total,Difference from [Archive$]Where Total=104") to Spreadsheet 2


Please note , I'm using Visual Studios 2008 (not sure if that matters).

Thank you in advance for your help on this.

Please provide a full coded solution to this problem.

What code do you have?

EE is not here to build full applications but rather to help with questions you have with your efforts.

One thing to try to see the basic code is to record a macro
Start recording
Create the new spreadsheet
Copy one cell/row
Paste to the new spreadsheet

Basic algorithm for the program

Setup the data connections to the existing spreadsheet
Setup the SQL string
Open the connection
Create the recordset

Create the new spreadsheet
Set ROW = 1   or whatever you want as the first row
While there is data in the recordset
    NewXls.cells(row,1) = RS.Fields("Row")
    NewXls.cells(row,2) = RS.Fields("Total")
    NewXls.cells(row,3) = RS.Fields("Difference")
    Row = Row + 1
Wend

Close the recordset
Close the connection
Save the new spreadsheet
