Creating Custom Date Function in Excel - excel

I am trying to code a date function in Excel using the Month and than the last two digits of the year. So for example I just have the numbers 1-12 in a column. Then I want to code them as follows. 1 is Jan-15, 2 is Feb-15,..June-15. Then 7 is July-14, 8 is Aug-14. However whenever I try to type in those it codes them as their respective month, the day and the year as 2015. I know I have to create a custom format date function, but how would I go about doing that in this case. I have seen some things, but many of times it is unclear. Could Someone help me out.

Create a custom date format
If you want to use a format that isn’t in the Type box, you can create your own. The easiest way to do this is to start from a format this is close to what you want.
Select the cells you want to format.
Press CTRL+1.
In the Format Cells box, click the Number tab.
In the Category list, click Date, and then under Type, pick a date format that is close to the format you want.
Go back to the Category list, and pick Custom. Under Type, you’ll see the format code for the date format you picked in step 4. The built-in date format can’t be changed, so don’t worry about messing it up. The changes you make will only apply to the custom format you’re creating.
In the Type box, make the changes you want using code from the table below.
According to the table there and your description I suppose you should use a custom format like:
mmm-yy

How to properly format dates in Google Sheets or Microsoft Excel

I have a spreadsheet I need to make in Google Sheets. The source of some of the data is exported to an Excel sheet. The data arrives in a dd/mm/yyyy format and I need to display it in a MON d format (Ex Sep 5).
The problem is both excel and sheets look at the date that arrives and think it is mm/dd/yyyy.
For example, 02/08/2022 is believed to be Febuary 8 even though it should be Aug 2. The problem then arises that neither of these platforms end up knowing how to convert this to Aug 2 and I end up having to do this manually.
Does anyone know how to get around this?
I have tried adjusting the format of the date, as well as using DateValue to convert (this fails since it understands the date as mm/dd/yyyy even when it is dd/mm/yyyy).
Any leads would be appreciated!
Thanks!
In Google Sheets, choose File > Settings > Locale and select a locale that uses the dd/mm/yyyy date format, before importing the data. You can then format the date column the way you prefer.
in gs:
=TEXT(REGEXREPLACE(A1&""; "(\d+)\/(\d+)\/(\d+)"; "$1/$1/$3"); "mmm d")
Try the following and format the result to your liking
=INDEX(IF(ISNUMBER(U2:U5),U2:U5,
IF(U2:U5=DATEVALUE("1899-12-30"),,
(MID(U2:U5,4,3)&LEFT(U2:U5,3)&RIGHT(U2:U5,4))*1)))
(Do adjust the formula according to your ranges and locale)
Functions used:
INDEX
IF
DATEVALUE
ISNUMBER
TRUNC
MID
LEFT
RIGHT
Well, for a formulaic solution, if the date is in A1, then the following places the correct date in B1:
=DATEVALUE(TEXT(A1,"DD/MM/YYYY"))
The TEXT function makes a string that will be the same form as your imported string out of the date produced during import. DATEVALUE then gives the proper date you desired.
The trick is in the TEXT step in which you reverse month and day in the string for DATEVALUE.
Naturally, instead of a helper column, it could just be wrapped around any reference to a date from column A, though one would have to remember to do so for all the years the spreadsheet is in use.
If you are importing, not just opening a .CSV file via File|Open and going from there, you have an opportunity to solve all your problems. You use the Ribbon menuing system's Data menu, select the very leftmost thing, Get Data and from the (no arguing THIS isn't a menu) menu that drops down, Legacy Wizards, then finally From Text (Legacy) which will open the old Excel Import Wizard. (You may notice this is very like the Data|Text to Columns Ribbon menu choice and that is because that choice is the old wizard minus the steps at the start that go looking to another file for the data because it knows, by law, that it has to already be in the spreadsheet... in other words, it looks the same because it IS the same.)
Then make selections for the first couple dialogs it presents you to get to the dialog in which you tell it to import columns as whatever: general (let Excel decide), text, date, and do not import. Choose Date and make the selection of DMY to import them properly as you desire them to be so you are never presented with the problem at all.
As you might guess, you can use the abbreviated wizard via the "Text to Columns" feature to do the same thing after import when you see they are reversed. Since it is a single column of data, the result will overwrite the original simplifying your work.
Why does this happen at all? Well, the "locale" folks have the idea. When Excel imports numbers that are in a form it recognizes could be a date, it looks to the operating system settings for the selected ways dates are understood. So if your operating system believes a date should be displayed "Month Day, Year" and Excel has a set of data it thinks fits that mold, it will convert them all using it. So you get those Feb 8's rather than Aug 2's.
Interestingly, it does two other things of note:
It looks at 8, count 'em, 8 rows of data to decide the data fits the pattern. Even with 1,000,000 rows to import, it looks at... 8.
Then it does them ALL as if God himself wrote the "8"... and dates like 25/03/2022 get imported as text not a real date, because they (oh, obviously) can't be dates... "25" can't be a month!
It IS possible to change settings (DEEP settings) to make Excel consider X number of rows in a data set before deciding such things. I found them here, on the internet, once upon a time, though I shouldn't like trying to find them again. It will consider up to a million rows in such an import, but... that'd make it pret-ty slow. And that's a million rows for EACH data column. I won't even say that "adds up" - I'll point out it "multiplies up."
Another technique is to add some number of starting rows to force the desired pattern onto the import. I've heard it works in TIME column imports so it ought to in DATE column imports but I've not verified such.
My bet is you will find the use of the "Text to Columns" feature of most use if you can use a hands-on approach - it does require literal action on your part, but is a fast operation. If you will see others using the spreadsheet though... well, you need a formulaic solution or a VBA one (macro with button for them to have some fun clicking as their reward for doing what they were trained to do instead of complaining to the boss you make bad spreadsheets). For a formulaic solution, the above formula is simple.
Last thought though: there's no error-checking and error-overcoming in it. So a date like "25/03/2022" in the data that imported as literal text is a problem. For handling the latter, an up-to-date approach could be:
=IF(TYPE(A1)=1,DATEVALUE(TEXT(A1,"dd/mm/yyyy")),DATE(INDEX(TEXTSPLIT(A1,"/"),1,3),INDEX(TEXTSPLIT(A1,"/"),1,2),INDEX(TEXTSPLIT(A1,"/"),1,1)))
in which the DATE(etc. portion handles finding text of the "25/03/2022" kind. Lots of less up-to-date ways to split the text Excel would have placed in the column, but since demonstrating what to do if it existed was the point, I took the easy way out. (Tried for a simple version but it wouldn't take INDEX(TEXTSPLIT(A1,"/"),1,{3,2,1}) from me for the input parameters to DATE.) TYPE will give a 1 if Excel imported a datum as a date (number), and a 2 if brought in as text. If empty or strange strings could exist, you'll need to deal with what those present you as well.

Fetching date value from a SharePoint-list, to use in date&time specific field in flow

I'm trying to design a Microsoft Flow, which will create a outlook calendar event entry based on information in a SharePoint-online list.
The list will contain a value for a DueDate its a column of type Date, not including time.
I want to be able to create a outlook calendar entry on the date based off the duedate column. The calendar entry form in flow allows via dynamic content to add dates that also include time, however date columns not containing time cannot be added that way.
Is there a workaround to this, some expression that would allow me to fetch values from columns more freely and then possible append a time to it
I have tried converting the column in sharepoint to a Date with Time column and that workaround worked, however its not what I'm looking for. Id like to know how to be able to work around this because I don't necessarily want my column as a date-time column which can cause problems later on.
I have tried this expression:
formatDateTime(concat(item()?['DATE'], '08:00')'yyyy-MM-ddThh:mm:ss')
But I know this is wrong and it doesn't work. I'm simply not sure how to do it.
https://puu.sh/Df5ni/05cb882b23.png
I want the flow to add a calendar entry based off the due date column which i can append my own time to like the start of the day and last til the afternoon.
Actual results are I don't seem to be able to use a date column, just a date-time column for start and end times of the event, date column without time doesnt appear in the dynamic content list.
If there is some way to manually fetch values instead of using the dynamic content that is very powerful and can then possibly be converted to the right format using additional code.
Date column name in my list is date_without_time of type Date (Add time set to NO):
New element:
Function used in Create event (V2) action:
formatDateTime(triggerBody()?['date_without_time'],'yyyy-MM-ddT09:35')
Result:
Calendar:

Can't convert Date to Number

I have a userform and I take start and end dates from user as in dd.mm.yyyy format. To make it easier to compare dates, I want to turn it to a double or long type of value. I have tried as in below but it gives me an error of type mismatch.
endDate is already defined as Double and as you can see, Me.g_end.Value is string in proper format. Why do I get this error, and how can I handle it?
Also I need to add, DateValue(Me.g_end.Value) works fine with my friend to get value of date who uses Excel 2013. I use Excel 2016.
You need to enter dates in a valid format in order for Excel to recognize them as dates.
As far as I know, nowhere uses dots (periods) in dates. (As I recall, nowadays only one country in the world even recognizes dots as am official date separator.)
Click your Start menu and type Region to find and open Windows Region and Language Settings.
Note the format that your system is expecting for Short Date, including the symbol between each date part, and try entering your dates in Excel like that.

MS Excel Time Format (Not Function)

I am having a problem with Excel's time format. I am trying to log amount of time spent on things. (and i want to be lazy) I try logging the time and excel converts it to a date. I know why it does this, but not how to stop it. I have even tried a custom format so that excel wont convert it, but excel somehow overrides my customization. Im trying to log four minutes and 24 seconds. i have tried doing 00424, 000424, 424, and a few others. I have tried 4:24 and excel changes that to 24:00. like i said, i have tried customization and i have tried pre-made formats, but nothing fixes it. Preferably i'd like to be lazy and just type in 424 and have it converted to 4:24. Any help?
Thanks, Greg
Use two columns, A where you enter values, B where you display them.
In B1 and below put:
=(INT(A1/100)*60+MOD(A1,100))/60/60/24
Then format column B as custom M:SS
Change the formatting of the cell to "Text" .. then type whatever you want: ie "4:24", "424", "0424", etc all work. No fancy formatting, but the data is in. Next, take the next cell and parse/format it (again in text) the way you want: So if you're input is simply "424" (in A1) as you want ... just do a: =concatenate(mid(a1,1,len(a1)-2),":",mid(a1,len(a1)-1,2))

Some but not all Excel numbers show as a date

I have a big .xls file. Some numbers show as a date.
31.08 shows as 31.aug
31.13 shows as 31.13 (that is what i want all columns to be)
When I reformat 31.aug to number it shows as 40768,00
I have found no ways to convert 31.aug to 31.08 as a number. All I am able to do is to reformat 31.aug as d.mm and then it shows as 31.08 and when I try to reformat it from 31.08 to number it shows as 40768,00. No way to cheat Excel using different types of cell formats.
How's your regional settings? There are some Regions where the short date is identified by dd.mm.yyyy. (Estonian, for instance). Maybe if you change the regional settings for US / UK and paste the data again it won't be changed.
Worked in a small test I did here. Hope it helps.
Internally Excel stores Dates as integer. 1 is January 1. 1900. If you entered something that Excel interprets as a date then it will be converted into an integer. I think from this point on there is no way back.
There is an setting in Options on the tab "international" where you can define your decimal separator. If you set this to ".", then your Excel should accept 30.12 as decimal number and not as date.
As pointed out by others, Excel interprets some of your data as a date instead of a number, which depends on your regional settings. To avoid this happening try Tiago's and stema's responses, they will work depending on your regional settings.
To repair your problem in a large file after it has happened without re-entering/re-importing your data, you can use something like
=DAY(B5)+MONTH(B5)/100
to convert a "date" back to a number. Excel will still display it as a date when you first enter this, but when you reformat it as "Number" now it will display the value you originally entered.
Since your column seems to contain a mix between correct numbers and dates, you need to add an if() construct to separate the two cases. If you haven't changed the display format yet (i.e. it still displays 31.Aug) you can use
=IF(LEFT(CELL("format";B7);1)="D";DAY(B7)+MONTH(B7)/100;B7)
which checks if the format is a "D"ate format. If you have already changed the format to Number, but know all your correct data is below 40000, you can use
=IF(B5>40000;DAY(B5)+MONTH(B5)/100;B5)
As suggested above, go to Control Panel - Region and Language - Advanced Settings - Numbers - and change the Decimal Symbol from "," to "."
Good luck!
The data you are pasting, is it by any chance a pivot table.
For example, like you, I am copying a lot of data into a large spreadsheet. The data I am copying is from another sheet and it is a pivot table.
If I paste normally, half will show up as numbers, which they are in the source file and half will show up as dates, for no reason, which drives me insane.
If I Paste->Values however, they will all show up as numbers, and as I don't need the pivot functionality in the destination file this solution is fine.
All you have to do is format cell.
1-right click on the cell where you want to insert the number.
2-then click on Number and select 'General' from the number menu.
Hope this will help future people with the same issue.
