A spreadsheet is the wrong tool for everything, but it’s also a very available tool. No results came up when I was searching for how to join data sets in different ranges in a Google Sheets or Excel worksheet, so here’s how you do it.
Suppose you have these three data sets in a Google Sheets worksheet:
| Key |
| Aardvark |
| Aardwolf |
| Aaron |
| Key |
| Aardvark |
| Koala |
| Zebra |
| Key |
| Aaron |
| Abdullah |
| Alice |
How do you join them and list the unique elements on a different sheet? You want something along the lines of this formula:
=index(sort(unique({sheet1!A$2:A$4; sheet2!A$2:A$24; sheet3!A$2:A$4; })),row()-1)
{range1; range2} joins the contents of multiple ranges into a union
unique eliminates duplicates, sort() is self explanatory, and index(range, i) gets an element
The output should be something like this:
| Key |
| Aardvark |
| Aardwolf |
| Aaron |
| Abdullah |
| Alice |
| Koala |
| Zebra |
