What we'll do is take our reordered columns from last time and write them back to a CSV file. The first job is to find a way to reference the cells on the spreadsheet that we want.

We can then loop round all these cells getting the values. Our spreadsheet is 3 columns wide by 8 rows high: We could have two loops to cycle through the data above, an inner loop and outer one. This is the number of rows we have.

The inner loop goes from 1 to 3, which is the number columns. However, suppose we decided to add more rows, or more columns to the spreadsheet. It would mean our loop would not pick up the new data.

A similar technique is used to find the last column with data. The technique we prefer, though, is this: Row This refers to any range in your active worksheet with data in it. The inbuilt SpecialCells is then used. This gets you the last cell with data.

After a dot, you can type either Row or Column, depending on which last cell you want. We're almost ready to start writing the code. To actually open a text file for writing, though, you need this: VBA will then try to open up your file. If a file of the one named in FilePath doesn't exist it will be created for you.

If the file does exist then it will be overwritten. If you want the new contents to be added to the end of your file then you would use Append instead of Output. To do the actual writing to the file you need this: After a comma, you need the contents you wish to write to the file.
