How to create a distribution plot

Dear All,

I am very new to this forum (this is my first post), and a fresher with Excel (so far I used more specialized software like Sigma and Origin, programming with C++ in their environment). Yet, I have never made a macro in Excel yet.

This is my problem: I have several worksheets with thousands rows (independent variables) and hundreds columns (all dependent variables). Each line basically gives me hundreds values for each independent variable - see below:
...
C9 39.65 653.95 5.28 163.56 99.56 14.49 ... ...
E9 7535.92 21500.56 2835.88 3122.98 7225.34 5371.25 ... ...
G9 111568 298021 12940 31645 181797 36996 ... ....
...

I need to know how the values in each row are distributed, and I ideally plot a 2D column graph of the distribution. Is there a way to do that and create/program a macro (with relative button on the workboook) that does it automatically once clicked?

Very often there are outlying values (bigger or smaller by a factor of 1000 or even more), mistakes, which I would like to identify and fix possibly.

Can I program excel to do that?

Thanks in advance...

Am I really asking for something impossible?
