How can I force PowerQuery to load the table formatted as "Text", even if some cells contain only numbers?

[Want2BExcel]

I have this problem with some data. Some suggested it could be a PowerQuery problem.
I have a table containing serial numbers and a lot of other data. The table is created through a power query that pulls the data out of an access db.
In the Access DB the data is entered as "short text", because serial numbers often includes letters.
In the PowerQuery the data is recognized as text "ABC"

even if some cells contain only numbers, but when loading it into a table, the formatting is "Standard" which causes a problem. I tried changing the whole column to be formatted as "Text" afterwards, but it doesn't help, since this should be done prior to entering data. I tried formatting the columns to text before loading the table, but when loaded it is again "Standard". Is there a way to make the loaded table formatted as "Text" and not "Standard"?

The table has more than 5000+ rows but for 8 of these rows the data is a very long serial number, only containing numbers. For some reason Excel treats all cells that contain only numbers as numbers and not text and for these 8 cells it creates a problem because of the length. Excel is putting in a comma (9,88........) and because Excel can only store up to 15 significant digits. It converts any others after that to zeros ("0"). But those last 3 digits, if you look at the serial numbers in green, is exactly thoos 3 that makes every serial unique.
This is a problem for me in other parts of my workbook where I use a COUNTIF formula to verify that there a no duplicates in any serial numbers. But because of Excel's way of handling the data in those 8 cells I get a result of 6 duplicates, which is incorrect.

Any ideas how to resolve this?

COUNTIF is the problem there, not power query. Use sumproduct instead.

Can't see how SUMPRODUCT should help? I get an #VALUE error

=COUNTIF(SOURCE_DB[Serienummer],SN_LIST[Serienummer])

= 6 (because it only "reads" the 15 first numbers 988169234001149xxx. I need it to look at all the numbers so that 988169234001149491 = 1)
VS.

=SUMPRODUCT(SOURCE_DB[Serienummer],SN_LIST[Serienummer])

= #VALUE

 

[RoryA]

Use:

=SUMPRODUCT((SOURCE_DB[Serienummer]=SN_LIST[Serienummer])+0)

 

[Want2BExcel]

Use:

=SUMPRODUCT((SOURCE_DB[Serienummer]=SN_LIST[Serienummer])+0)

The result just gives an #I/T error on all 5000+ rows

I don’t know what that error is. What language is your excel in?
If you just apply the formula for one cell of the second range, what do you get?

It a danish version. I think the #I/T error in this version correlates to #N/A in english version (Excel ERROR: #I/T (#N/A)

If I just apply the formula for one cell of the second range, I get the result I'm looking for =1

...so it seems like it can't process the whole column SN_LIST[Serienummer] in the other table That seems weird...

It wasn't quite the solution I expected, but nevertheless it works.

Thx for the attention, your time and solution RoryA
