From the Not Just Numbers blog:
Before I get into today’s post, just a quick reminder for those of you in London about the Twenty Principles event I mentioned in my last post.
I believe that there are still some places available for Wednesday evening, and it would be great to see you there.
I am currently working on a large project trawling through some incredibly complex spreadsheets built by someone else, and I thought that I would share with you a simple, but very valuable Excel feature that I am using a lot on this project.
Before I can make decisions about any particular cell in the spreadsheet, I need to know how it is linked to other cells.
These links go in both directions. If the cell contains a formula, I might want to know what other cells this cell is dependent on (referring to the formula will help in this case).
The contents of the cell will be of no help with the other direction, and this is the one I need to know most often, i.e. what cells are dependent on this one. This is crucial, because I can’t delete it or change it, until I know if there are any implications, and if so, what they are.
Fortunately Excel has a tool for both of these.
On the Formulas ribbon, there is a section called Formula Auditing which includes, among other things, the following three buttons:
- Trace Precedents
- Trace Dependents
- Remove Arrows
