index match, multiple columns/array with date, strings and blank cells

[lukasvjohansson]

Hi,

I have a problem regarding a structure for project management and specifically deadlines.

On the rows I have different customers/projects which each have columns with different activities, e.g.:

Project/Customer	Deadline activity 1	Deadline activity 2	Deadline activity 3	Deadline activity 4	...
Customer 1	2019-02-28	2019-03-05	2019-03-07
Customer 2	YES	Not possible	2019-03-01	2019-04-02
Customer 3	YES	2019-01-02	YES
Customer 4	YES	2019-03-02	2019-03-13
Customer 5	YES	YES		Not possible
Customer...	YES	YES		Not possible

<tbody>
</tbody>

For example, the data could look like this. Where yes indicates a finished deadline, not possible is an activity that is not possible to perform, and for the blank cells there is not a deadline in place yet, but will be added later. Dates that has already passed may be still kept in the table, like in activity 2 and customer 3 in the example above. I have already applied a conditional formatting on this table, but now...

... I would like to create a separate ranking table of, for e.g., the top 10 most pressing activities, regardless of customer and activity:

Ranking	Customer	Activity	Date
1	Customer 1	Deadline activity 1	2019-02-28
2	Customer 4	Deadline activity 2	2019-03-02
3	...	...	...
4
5
6
...

<tbody>
</tbody>

Ive tried with =SMALL function and using the ranking as the N.th smallest date, but realised that since old dates might be included, the difference from TODAY() function is probably most applicable to get which date is coming up next. Ive made som progress with MMULT function, but at that point things got a bit too complex for me. My greatest challenge seem to be that the table that should be modified includes date, strings and blank cells. And since date is just a format and is still seen as number, I have a hard time separating them.

Any suggestions would be greatly appreciated. Basically my need is to develop a easy, comprehensive to-do list that can handle multiple projects (about 50+) and multiple deadlines on many different activity types (>10)

Best regards

It would be good if the solution would function in Excel 2010, windows.

The to-do list table would of course be sorted on the date for the deadline, hence prioritised on the most pressing deadline-date, rather than the type of that activity or the customer.

And sorry for all the extra post, but can't edit anymore.

The data is currently not structured as a table, but rather just plain data. Please let me know if an actual table would help my purpose.

Perhaps something like this:

	A	B	C	D	E	F	G	H	I	J	K	L	M	N
1	Project/Customer	Deadline activity 1	Deadline activity 2	Deadline activity 3	Deadline activity 4	...				Ranking	Customer	Activity	Date
2	Customer 1	2/28/2019	3/5/2019	3/5/2019						1	Customer 2	Deadline activity 3	3/1/2019
3	Customer 2	YES	Not possible	3/1/2019	4/2/2019					2	Customer 4	Deadline activity 2	3/2/2019
4	Customer 3	YES	1/2/2019	YES						3	Customer 1	Deadline activity 2	3/5/2019
5d>	Customer 4	YES	3/2/2019	3/13/2019						4	Customer 1	Deadline activity 3	3/5/2019
6	Customer 5	YES	YES		Not possible					5	Customer 4	Deadline activity 3	3/13/2019
7	Customer...	YES	YES		Not possibl e					6	Customer 2	Deadline activity 4	4/2/2019
8										7
9										8
10										9
11										10

If entered correctly, Excel will surround with curly braces {}. Note: Do not try and enter the {} manually yourself

I changed one of the dates to show that these formulas handle ties.
