The fastest routine to copy & paste ~350 rows if cell1 matches a dynamic criterion?

[amq]

Hi everybody!

I've got to copy ~350 rows of data (individually) from one worksheet to another if the value of cell1 in the source row matches the cell1 value of the target row.

At the moment I am running two "For ... Next" loops within each other

As you can expect, browsing through 2x 350 rows and updating each of them in this way is not really high-performance code.

How would you tackle that? What's the fastest way to realize this?

Happy to hear your ideas!

Best regards,
Andreas

You can improve the "appearance" of efficiency by putting this above and below your loops:

You can use the Data > Filter to filter the data directly for all the rows matching the criteria, then move them enmasse. Your code appears to be parsing all the rows of data from one master sheet out to sheets that are named for those values. If that's true...



'SHEET1 TO MANY SHEETS
Here's a macro for parsing rows of data from one sheet to many sheets named for the same values in a specific column.

Sheet1 to Many Sheets

It not only can parse the rows, it can create the sheets if they are missing. There is a sample sheet there where you can test this out.
