Where we left it 2 weeks agao

2
We found duplicates with a pivot table

And replaced those with a VLOOKUP

4
There are other ‘problems’ here

5
A spreadsheet is not perfect for ‘repeatable’ analysis

But I want a filter

And another one

Suppose I need these two values

Manually filter

Don’t paste!

20
Use a...

21
Included in Office (Professional and higer) Definitely not the only database!

72
This relationship expresses that knowing

Access knows!

81
