I am pulling in date information via MySQL and the date is in the string format of "MM/dd/YY hh:mm:ss"
Using the built in conversion to date isnt working; so I tried using DATEPARSE and also using DATE and manually parsing it. I have had no luck and I have no idea why I keep getting "null" as the answer or it is putting the month as year, day as month, and year as day.
See screenshots below for the different formulas I have used:
DATEPARSE
Original date format
DATE with manual parsing
This worked for me using your example original data
DATEPARSE('mm/dd/yy hh:mm:ss',[Time] )
I used tableau's documentation of custom date formats to find the right formula for the format.
If this doesn't solve the problem then it is most likely due to a Locale issue. The Dateparse function relies on the locale specified by your computer settings to interpret and then display the strings you want to convert and can affect whether a certain format can be specified. This means that if a certain format is not recognised it will return a null. This will often occur is the windows region and language format is changed to another language other than the original language the workbook was created it.
So check your locale and if required execute the following workaround (documented by tableau here):
Open Windows control panel > region and language > format
Click format dropdown and change to original language of workbook creation
click ok or apply and reopen tableau work book

I am trying to convert a field that contains strings such as 202008, 202108 to a date field. I have tried the date() function, clicking on the measure and converting it to a date. I have also tried DATE(LEFT([Month],4)+"-"+RIGHT([Month],2)+"-01") but that will only return the year.
Using Tableau Desktop 2021.1, when I change the data type from String to Date, Tableau translates the strings to 8/1/2020 and 8/1/2021. If you are using an earlier version of Desktop, it is possible that this functionality is not present.
However, if changing the data type isn't working for you, the calculated field code you provided should actually work, you just need to change the date part from Year to Month/Day/Year using the Custom date part option.
I've pulled in data in Qlik Sense (cloud) from the Google Analytics connector. I'm trying to convert the standard date [ga_dateHourMinute] field to a more eligible date format.
The current format is YearMonthDayhHourMinute, for instance: 201810250004, I would like to convert this to the standard date format 2018-10-25 00:04:00. How do I do this? Answers concerning methods in the data load script or master formula's or variables are all welcome.
Click to see screenshot: left = current date format and right = desired date format
This is one approach:
DateAlter:
LOAD * INLINE [
Date
201810250004
];
DateAlter2:
LOAD
Date(Date#([Date], 'YYYYMMDDhhmm') ,'YYYY-MM-DD hh:mm') AS [MyDateField]
Resident
DateAlter;
If you haven't played around with the data manager, it will allow you to edit fields and handle dates in a fairly easy manner:

I ended up creating a text fields that combined the different digits from the one field into a new order, then pushed the data format into a date/time. Quite a bit of work, but fairly solid.
I have a Power BI file that connects to a data model via SSAS. The data model origin is a SQL Server view with some computed columns added in via SSAS.
One of the visualisations is a Hierarchical Slicer that shows dates. The field is not one of the computed SSAS columns. It displays in DD/MM/YYYY format but when I place the file on a Power BI Report Server the format is Americanised to MM/DD/YYYY. I want it to be DD/MM/YYYY.
The same field is used to populate a table visualisation but in there it remains DD/MM/YYYY. Just the slicer is affected.
This blog https://community.powerbi.com/t5/Desktop/date-format-in-slicer/td-p/215627 seemed to have the answer I needed but these settings were already applied and still the slicer shows MM/DD/YYYY.
Its not a problem when I open the pbix file locally; there, the slicer shows the dates as DD/MM/YYYY, its just when its on the server. The same problem persists in Test and Production and I have checked those settings and they are as the blog indicates. Other blogs identify this with the slicers but do not present a real solution as its not seen as a problem in those topics.
I've only spent a month working with Power BI so have no real experience to draw upon. I know that SQL Server defaults to American English when connecting to a database and I have changed that to British English but still the same problem. How do I get the slicer showing as DD/MM/YYYY as in my local copy?
Select the Date column and then go to the Modeling tab and change Format to whatever Date format you want.

You can create a calculated column using the FORMAT method in DAX to convert date format as you want.
See reference here: https://msdn.microsoft.com/en-us/library/ee634398.aspx
Power BI is missing the formatting in their recent releases. However, the below solution works for me:
Create a Calculated Column ref. the original Date column and apply "Short Date" format for Date, example:
Transaction Date =
FORMAT(DATE(
YEAR([Transaction_Date]),
MONTH([Transaction_Date]),
DAY([Transaction_Date])
), "Short Date")
I am using Tableau 9.3 to do a preliminary data analysis on one of my log file, the log file is like below:
"199.72.81.55",01/Jul/1995:00:00:01,/history/apollo/,200,6245,Sat
As you can see, there is a datetime for timestamp
In Tableau, initially it is recognized as a string like below:
That's fine, I want to make the field into datetime, and Tableau seems failed on it:
Why? How do I fix it?
Thank you very much.
UPDATED: after applying the formula suggested below, Tableau still cannot recognize the timestamp, here is the screenshot:
UPDATED AGAIN: after tested by nick, it is confirmed his first script is correct and working on his Tableau, why it fails on mine, I don't know, you are welcome to share any clue please, thank you.
Tableau implicit conversions are limited to more standard formats. You can still create a DATETIME field from your timestamp string using a calculated field with the following formula:
DATEPARSE('dd/MMM/yyyy:HH:mm:ss',[timestamp])
Using the above will transform a string like 01/Jul/1995:00:00:01 to a date and time of 7/1/1995 12:00:01 AM
Output using example data:
Sometimes the "date parse" function in Tableau doesn't quite do the job.
When this happens it is worth testing manual string manipulation with your timestamp field to put it into ISO-standard format and only then trying to convert it into a date. ISO format is yyyy-mm-dd hh:mm:ss (eg 2012-02-28 13:04:30). It is common to find that the original string has spurious characters or spaces that throw dateparse. But these are usually easy to manipulate away with suitable text manipulations. This can sometimes be longwinded, but it always works.
It turned out to be the region setting issue, it works after I switch it to USA
I have imported some data into SAS from some Excel spreadsheets sent to me. When I view the output from the imported table, the date appears as "01APR2014" and maintains chronological order. When I view the column properties the type is "Date" and the length is 8. Both the format and informat are DATE9.
I need to be able to convert this date to week-year and month-year, but no matter what I try I always get Jan, 1960.
Using proc sql, I used the below to get the week-year,
"(put(datepart(a.fnlz_date),weeku3.))|| "-" ||(put(datepart(a.fnlz_date),year.)) as FNLZD_WK_YR,"
but all I got was "W00-1960". I've used the formula above successfully many times before with SAS datetime values.
For month-yr, using proc sql, I tried
"datepart(a.fnlz_date) as DT_FNLZD format=monyy.,"
but the only value returned is "JAN60".
I also tried using SUBSTR, but got an error saying it requires a character argument, so SAS must see it as a number at least.
My question; does anyone know a way to get the week-yr and/or month-yr from this format? If so, how? I'm not opposed to using a data step, but I haven't been able to get that to work either.
Thanks in advance for any help or insight provided.
datepart converts datetimes to dates. Not helpful here.
If you're just displaying this, then you have a few options, particularly for month. You can just change the format of the variable (This changes what's displayed, but not the underlying value; consider this a value label).
When you use this like this (again, it looks like you got most of the way there):
proc sql;
select datevar format=monyy5. from table;
quit;
Just don't include that datepart function call as that's not appropriate unless you have a datetime. (Date=# of days since 1/1/1960, Datetime = # of seconds since 1/1/1960:00:00:00).
That will display it with MONYY5. format, which would be MAY10 for May, 2010. You have some other format options, see the documentation on formats by category for more details.
I can't think of a Week format that matches what you want (there are week formats, like WEEKW., as you clearly found, but I don't know that they do exactly what you want. So, if you want to build one yourself, you can either build a custom picture format, or you can make a string.
Building a custom picture format isn't too hard; see the documentation on Picture formats or google SAS Date Picture Format.
proc format;
picture weekyear (default=8)
low-high = 'W%0U-%Y' (datatype=date) ;
quit;
Now you can use that as a normal format.
To get at the week/etc. to build values, you can also use functions week(), month(), etc., if that's easier.
Since the data was already in a date format, I only needed to drop the DATEPART function that only works with datetime values. So, for month-yr,
"a.fnlz_date as fnlz_mnth format=monyy.,"
gives me the results I'm looking for.
Cheers!
