Convert Text to Date Format

New Contributor

Hello everyone,


I'm just an excel newbie and I've been finding ways on how to convert a date text string to date format. I find it peculiar that after transferring all my CSV files through a flash drive, then into another machine, my dates messed up but it was all in the correct format before. See attached photo below for the outcome. How do I fix this?

Hi Nina,

you can use this macro, see attached file to convert dates. It converts all dates in selection to real date.


Sub KonvertDate()
Dim rngCell As Range

For Each rngCell In Selection
rngCell.Value = CDate(rngCell.Value)
Next rngCell

End Sub

@Nina_SC ,

You may select your column, on ribbon Data->Text to Columns. On second step of the wizard select as delimiter any symbol which is not appears in you data


On third step select Date and MDY


It is assumed your default date format is m/dd/yyyy

Hi Sergei,

Thank you for your reply. I did what you have instructed but still no visible change though. Is there another workaround I could do? 





Your issue is common when going from data in one date format e.g. US to another e.g. UK / Australian


I did a video on it here on how Power Query in Excel can fix it



There's also a long formula solution attached..




One extra note to flag,  don't open then save your CSVs,  use Power Query to pull the data in without opening the original CSVs.


In your example most solutions will leave the circled values as 3rd January, 3rd February but I'm guessing the original dates were 1st and 2nd of March





@Wyn Hopkins Hi wyn, thank you so much for your suggestion. I tried applying it and used power query in power bi -- and after changing the locale still nothing has changed. The error was still there. I don't know where the error is coming from but would you mind taking a look at my file? It would mean a lot and thank you so much.



With Power Query click Data->From Table/Range (it'll be converted to table), Transform, in Power Query editor select all 3 columns, and from right click menu select Change Type->Using locale. Here Date and English (United States). Land the result back to the sheet.

Generate script is

    Source = Excel.CurrentWorkbook(){[Name="Table1"]}[Content],
    #"Changed Type with Locale" = Table.TransformColumnTypes(Source, {
        {"Created Time", type datetime},
        {"Last Update Time", type datetime},
        {"Close Time", type datetime}}
    , "en-US")
    #"Changed Type with Locale"

Please see Sheet2 in attached.

Hi @Nina_SC 


Unfortunately once you've saved the data in Excel all of those 1st of June dates have been already converted to 6th of January which is wrong.  Power Query can't fix this


What you need is the original unsaved CSV file and then use Power Query to pull that data in.


Do you have the original CSV you can post here?






If you don't have the original unsaved then you may need to use a formula approach like the attached



@Sergei Baklan 

I have a similar problem with internationally formatted data not being recognised as dates and times  or sort correctly.

The first set of date times are in PDT American format - 10/5/19 2:09:56 PM PDT

The second are in ISO 8601 format - 2019-10-02T03:54:00.000Z


I'm trying to find the feature that turns on Excel support for recognise these standard data formats so I can perform sort them and use them as an axis in graphs I want to generate.


I'm assuming that as the market leading provider of office based data manipulation and presentation tools Microsoft Excel would have implemented all the common international standards used for date and time date.
