training excel vba - Merge

Depending on the format, layout and content of the data you could use several techiniques:

1.
If the data is structured identically on sheet 1 and 2, then use CONSOLIDATE RANGES


2.
If the data is differently structured, then you may need to design a more tailored approach using other skills like 3-D formulas, or custom formulae.


I recommend reading through the Excel HELP file, specifically "About consolidating data", which wil detail the various ways you can approach your challenge.

Once you have done so, let us know if you find some next steps to work on.
