2 new tools have been added to JMT Excel Utilities.
Find Precedents and Dependents
An alternative to using Excel's built-in auditing tools. A form appears listing the addresses of all precedents or dependents of the active cell, including other worksheets or workbooks. Click on the the list entries to navigate to the precedents or dependents.
Find Circular References
Similar to the above but this list circular references only. You can click on the list entries to navigate to them also.
I have found them to easier to use than the built-in audit navigation arrows. You can download the most recent version of the utilities here.
