My data model has a column named rowDate. This column has several repeating instances of dates due to the fact that there are multiple rows of data for different times of a single day.
I've written a measure that sums the values in another column from the data model that I want to pull from. (We'll call this MyMeasure.)
I'm trying to write a CUBEVALUE formula that extracts the total of MyMeasure when rowDate equals the value of a cell in a worksheet. (This will allow the result of the CUBEVALUE to change based on the date that the user inputs into cell B2.)
e.g.
Cell B2 = "2018-06-29" (date formatted)
=CUBEVALUE("ThisWorkbookDataModel","[MyMeasure]","[Summary Data].[rowDate].["&$B$2&"]")
This always returns #N/A. I have another column with data (a number) that I can write the exact same CUBEVALUE formula, but referencing the appropriate cell, and it works just fine. It's just this date column that I can't figure out.
Found the solution in this thread. The trick is to format the date in your targeted cell inline using the TEXT function to match the cube's default date format (YYYY-MM-DDTHH:MM:SS).
=CUBEVALUE("ThisWorkbookDataModel","[Measures].[MyMeasure]","[Summary Data].[rowDate].&["&TEXT($B$2,"YYYY-MM-DDTHH:MM:SS")&"]")
I better show you. This is how my list looks like:
And this is how I want it to be:
Basically, in the first picture I have different date ranges, for each date range I have a those two metrics, Sessions and Users and the final result should be a sort of explosion of all date ranges into single dates, considering that certain dates can be included in more than 1 date ranges (e.g. date 2017-08-12) is included in both first and second row.
And last but no least, the end date shouldn´t be counted.
Can someone help me out?
Thanks a million

This is the outline of a solution:
Split each from/to date in your input table into its 2 constituent dates. You will need to use the string functions (LEFT, RIGHT and MID) to extract the numbers for the year, month and day values. These will still be strings of characters, so use the VALUE function to convert them to actual numbers and then use the DATE function to assemble them into a proper date value in Excel. (You may need to format your results using a date format, as Excel stores its dates as number of days since 01/01/1900, so 11/08/2017 is held in Excel as 42958.) Add as many helper columns as you need to your input table to achieve this.
Subtract 1 from each end date, this corrects the dates ranges so that the end date is included.
The first start date and the last end date define the range of output dates. So start your output table with the first date and in the cell below use a formula to add 1 to this date and copy the formula downwards until you get to your last possible output date.
To get the results for each possible output date, you need to find
which date ranges it belongs to. It belongs to a date range if it is
greater than or equal to the range's start date and less than or
equal to the end date. However, rather than comparing each output
date with individual start and end dates it is possible to compare
each output date with all the start and all the end dates at once. An expression such as A10>=E2:E7 generates an array of 6 elements with values
TRUE and FALSE according to whether A10 is greater than or equal to
E2, E3, E4, E5, E6 and E7 respectively. So, you can use this approach to generate an array of TRUE/FALSEvalues showing whether a particular output date is greater than or equal to (ie on or after) each range's start date. Similarly, you can get an array showing whether the same output date is less than or equal to (ie on or before) each range's end date.
The versatile SUMPRODUCT function can now be used to combine the arrays and the relevant sessions/users values from the input table to get the relevant values for the output date. For example, if the start dates are in E2:E7, the end dates in F2:F7, the sessions in B2:B7 and the output date in A10 then a sutable formula for determining the number of sessions to attribute to the output date would be =SUMPRODUCT(($A10>=$E$2:$E$7)*($A10<=$F$2:$F$7)*(B$2:B$7)). This formula could be copied to give results for all output dates and, assuming the input data for users is in C2:C7, it will also give the results for users if copied into the column adjacent to the sessions results. In this formula, the TRUE and FALSE values are effectively converted to 1 and 0, respectively.
A few points: (i) if you don't know how dates work in Excel then find out, it makes tasks such calculating the number of days between two dates or the date n days before/after a particular date extremely easy using simple arithmetic; (ii) don't confuse strings of text which look like dates with dates that can be manipulated arithmetically in Excel; (iii) I believe there are some errors in your example - 16/08/2017 is a date in two of your input ranges and should have results of (2,2) not (1,1) and 17/08/2017 is similarly in error.
I have used this approach in the illustration below and, to test its robustness, I have added an extra row of input data which has sessions different from users and which yields one date (19/08/2017) which does not match to any input range.
The output date range was generated as follows:
Cell A10: use formula =E2
Cell A11: use formula =1+A2
Cells A12, A13, ... copy formula in cell A11
I have a cell that has the formula =INDIRECT(CHAR(COLUMN()+65)&ROW())*MONTH($A$1)/12 where INDIRECT references an integer and $A$1 is a date. For some reason, the MONTH part converts the entire cell into a date instead of a number. How do I change the formula to have it return a number in number format? (Manually changing each cell through the ribbon is not an option for me).
I haven't tested this (and I can't comment till I get 50 rep), but you could wrap the whole thing in a text formula, then multiply by 1:
=TEXT(INDIRECT(CHAR(COLUMN()+65)&ROW())*MONTH($A$1)/12,"#")*1
Hope this helps!
Short story short:
I want to check the cell C21 if it contains a date. I can't use VB cause it's deactivated by GPO.
Used this from this page
D21 contains this:
=WENN(ISTZAHL(DATWERT(C21));"date";"no date")
in english
=IF(ISNUMBER(DATEVALUE(C21))...
C21 this:
=HEUTE() # in english: =TODAY() Maybe other dates later, but allways in the correct format
but it allways returns "no date"
Use this: =IF(LEFT(CELL("format",C21))="D",..,..). Learn more about CELL formula here.
In your example =TODAY() already a real date and not a date stored as text, so doesn't make too much sense to use DATEVALUE there.
Update
Here are some example dates and how CELL recognize them:
format value output
dd/mmmm/yyyy 12/June/2015 D1
dd/mm/yyyy 12/06/2015 D1
yyyy 2015 G
general 2015 G
dd/mm 12/06 D2
mmmm June G
dd mmmm yyyy 12 June 2015 G
Note: CELL is not volatile, so if the format of source cell is changed it won't be refreshed automatically, you need to either recalculate your sheet / book, either open the formula and press enter (also automatice recalculation initiated by any other volatile formula will cause it to refresh).
Use this formula, the expression will return TRUE if cell A1 contains an invalid date.
=ISERROR(DATE(DAY(A1),MONTH(A1),YEAR(A1)))
This formula works by evaluating each component part of the date: DAY, MONTH and YEAR and then aggregating them using the DATE function.
ISERROR will the catch any errors by returning TRUE (invalid) otherwise FALSE (valid).
Obviously the date value in cell (A1) must contain values >= 01/01/1900.
Useful for "Conditional Formatting".
Excel stores dates as numbers. 1 is 1-Jan-1900.
When it comes to numbers in a cell, Excel cannot tell if a number is meant to be a number or a date.
Today is 11/06/2015 as a date and 42166 as a number. For the consumer of a spreadsheet, the cell can be formatted to display the number as any number format or as a date. Excel formulas cannot tell whether the number in that cell is "meant" to be a date.
So, there is no Excel formula that you can use in a spreadsheet that will tell you if cell A1 is about 42166 widgets or if contains the date of June-11-2015.
Some of provided answers, checks cell format, which will not considers cell value, as you can format differently each cell no matter of its content, for checking if a cell value is date you can use this:
if(ISERROR(VALUE(c21)),"No Date", ----do staff for Date ----)
or shorter version which just will inform you "no date" status. If a date entry is find, it will return its numerical value instead:
IFERROR(VALUE(c21),"No Date")
hope this helps,
Cheers,

use the following formula ...
=IF(NOT(ISERROR(DATEVALUE(TEXT(C21,"mm/dd/yyyy")))),"valid date","invalid date")
I think it will solve your problem.
If the value is a string this method would work.
TEXT(DATE(VALUE(RIGHT(AI8,4)),VALUE(MID(TRIM(AI8),4,2)),VALUE(LEFT(AI8,2))),"dd.mm.yyyy") = AI8
Just wanted to add to the discussion that although you can check with a date(year;month;day) it will give you false positives, since the way it works is that it seems to just roll over values that exceed the logical limit, i.e. if you have the date 99-12-35 it will assume that you meant to write Jan 4th 2000, since that is the 35 - the 31 days of December. In other words, you will find some errors, but not all. Same goes for months exceeding 12.
try this formula (depends on date format):
=IF(DATE(TEXT(C21;"yyyy");TEXT(C21;"mm");TEXT(C21;"dd"));"contains date";"doesn't")
I tried every solution posted but none of them work if there are empty cells in the date cells, so I added a check to GBGOLC's answer and now it works with empty cells:
=IF(NOT(OR(ISBLANK(C21),ISERR(DATE(DAY(C21),MONTH(C21),YEAR(C21))))),"Yes it is a date","Not a date")
I have 2 cells, one cell has just text A1 cell, text (hello) other cell B1 has a timestamp (3:55). I need to combine these cell to one with this format: hello#t=3m55s, or if timastamp is 1:12:11 format will be hello#t=1h12m11s. So cell A1 will change to this specific format base on B1 cell.
Thank you.
You could try this formula:
=A1&"#t="&IF(HOUR(B1)=0,"",HOUR(B1)&"h")&MINUTE(B1)&"m"&SECOND(B1)&"s"
The & concatenates each part together. However, if the timestamps are not correct for the mm:ss times, then it won't work.
EDIT: To deal with the issue of timestamps:
=A1&"#t="&IF(SECOND(B1)<>0,HOUR(B1)&"h"&MINUTE(B1)&"m"&SECOND(B1)&"s", HOUR(B1)&"m"&MINUTE(B1)&"s")
The issue with this is that it won't work for timestamps of the type "11:11:00" But I don't think there's much to be done, unless the string is first converted to text, which I could give some pointers on.
