Excel advanced formula

[mcoll]

Here's the thing:
I'm making a list of all threatened species found in Conservation Units of Sao Paulo (Brazil). There are a few categories that species can be included when we talk about their conservation status:
- EX (Extinct);
- EW (Extinct in the Wild);
- CR (Critically Endangered);
- EN (Endangered);
- VU (Vulnerable);

There are 11 criteria. Every threatened specie has one or more criteria that defines its conservation status. For example: Habenaria schwackei (Barb. Rodr.) has criteria 3, 4 and 9. Thus it is an EN (Endangered) specie.

To define which category the specie belongs, we consider the following criteria:
- If it presents Criterion 1 = EX
- If it presents Criterion 2 = EW
- If it presents Criteria 3 AND 4 AND X AND Y other criterias (both between 6 and 11) = CR
- If it presents (a) Criteria 3 AND 4 AND X other criterion (between 6 and 11) OR (b) Criteria 3 OR 4 AND X AND Y other criterias (both between 6 and 11) = EN
- If none of those = VU.


Is there a formula that can represent this idea on Excel?


Thanks a lot!

It certainly should be possible with some IF statements, however, more information is needed.
How is your criteria stored in Excel now?
Are there 11 columns with some sort of marker in them:
i.e.

Specie</SPAN>	Status</SPAN>	Criteria1</SPAN>	Criteria2</SPAN>	…</SPAN>	Criteria11</SPAN>
A</SPAN>	??</SPAN>	YES</SPAN>	NO</SPAN>		NO</SPAN>

<TBODY>
</TBODY><COLGROUP><COL><COL><COL span=4></COLGROUP>

or is the Criteria data stored in a single cell as text
i.e.

Specie</SPAN>	Status</SPAN>	Critiera</SPAN>
B</SPAN>	??</SPAN>	3,4,9</SPAN>

<TBODY>
</TBODY><COLGROUP><COL><COL><COL></COLGROUP>

This information is necessary to develop a solution without wasting time.

The criteria data is stored like this:

Specie	CR	CR	CR	CR	CR	status
A	3	4	9			??
B	1					??
C	3	4	9	...	11	??

<tbody>
</tbody>

All those "CR" are, actually, merged in one cell, called "Criteria"

I can arrange cells in your first arrangement suggested, if necessary. i.e.

Specie	Status	Criteria1	Criteria2	…	Criteria11
A	??	YES	NO		NO

<tbody>
</tbody>

OK, given you can adjust the data in columns A:L as I outline below, the following formula should work.
Formula pasted in cell M2 and dragged down
=IF(B2,"EX",IF(C2,"EW",IF(AND(D2,E2,SUMPRODUCT(--(G2:L2))>=2),"CR",IF(OR(AND(D2,E2,SUMPRODUCT(--(G2:L2))>=1),AND(OR(D2,E2),SUMPRODUCT(--(G2:L2))>=2)),"EN","VU"))))

Note: The FALSE values are unnecessary and for ease of reading, can be replaced with "", but the TRUE values must be the logical result of some formula and not a TEXT value of 'TRUE
