Blocked files problem

Recently (I write this in August 2016), Microsoft has "enhanced" security and is now blocking any files that are downloaded from the internet. This means that any add-in you try to open after downloading will simply not open in Excel (without display of a warning message!). To resolve this, follow these steps:

1. Copy the add-in from the zip file to any folder

2. Right-click the xla(m) file and choose properties:

Select file properties

3. Click the Unblock button:

Click Unblock

Hi, many compliments for the addin I'd find it very useful in the Precedents feature, to see the value of the precedents not as ".value" but as ".text". So for example, if a precedent has a value of 1253514,254, but is shown (through formatting) as 12,5 (millions), it would be much better to see it in the precedents window as 12,5 than 253514,254 (as it is today). Thanks!

Hi Raffaele,

Nice suggestion, thanks.

Hey Jan Karel

I bought your RefTreeAnalyser and its a great tool and I use it when I have a doozy of a formula.

Lately I have been getting the msg upon opening Excel when it loads Add-ins that checking for updates as failed. I guess I could unclick the check for updates automatically but has the support for this add-in now stopped and that's the reason?

I could send you a screen shot if you want.

Hi John,

RefTreeAnalyser is still fully supported indeed and I'm working (slowly) on version 3.

So I guess the problem is on your end. Perhaps a setting in your firewall?


Comment by: John (7/23/2017 1:32:15 PM)

Hi again Jan Karel, OK will try that.

Sorry I didn't know this comment was going to be public and gave my license no. in the above comment, so please delete/redact it. thanks John

Hi John,



Comment by: Den (8/6/2017 12:14:54 AM)

Hi Jan,
there is an error in tracing when i use named table with name in cyrillic characters. If I use the named column with сyrillic, there is no error.

Some suggestions for next release:
1)In the interface, select the structure of the formula (not just each individual element) and display the calculated value for each block. If the formula uses a logical expression to calculate the result, display how the elements of the compared block match the condition (select suitable ones). If you use the array formula in the condition, display the matching array elements.
2) If the formula uses ranges / arrays of the same dimensions, display the array elements under each other. That is, it is necessary to align to the widest value of the element of the array / range group.
3) Make it possible to correct the formula via the add-in interface.
4) Connect the add-in to all Excel windows in which you entering the formulas:
a) Conditional formatting formula;
b) Data validation formula;
c) Formula for the named range in Name manager.
To check the operation of the formulas in these blocks, it is necessary to select the cell with which to calculate the formula. It is especially important when the formula uses an offset.

Thanks for the excellent add-on and further success!
