How to Convert Text to Dates

Sometimes when we import data from another source in to excel, the dates are not imported properly. This can be due to any number of reasons, including,

  • The date format is different from one that is understood by excel
  • The data has some extra spaces, other characters before and after the date values.
  • The dates are formatted for another country (or date system) and hence your version of Excel wont recognize them.
  • The separator between date, month and year is not a known separator (for eg. 12=DEC=2009 instead of 12-Dec-2009), etc.

In this post, we will learn some tricks and ideas you can use to quickly convert text to dates.

Technique 1: Use Text to Columns Utility

  1. First copy the source data and paste it in a text file (open Notepad and paste there).
  2. Now copy the values from text file and paste them in Excel.
  3. At this point, Excel will prompt you for using “Text to columns” utility (or Text Import Wizard as it is called in Excel 2007)
    Text to columns utility (Text Import Wizard) Prompt
  4. Go to the Text Import Wizard (or Text to Columns dialog).
  5. Leave defaults or make changes in step 1 & 2.
  6. In step 3, select “Date” and specify the format of the date – like YMD, MDY, DMY, YDM, MYD or DYM. It doesn’t matter what is the format of source date, month or year is. Excel can smartly understand them.

  7. Click “Finish”.

That is all. Your text dates are now converted to excel understandable dates.

Technique 2: Using Formulas to Convert Text to Dates

  1. Paste the data in a column (say “A”)
  2. Now depending on the format of source data, write one of the below formulas to convert text to dates.

Using DATEVALUE formula

DATEVALUE formula tells excel to fetch the date from a given input. It is a smart formula capable of converting dates stored as text to excel understandable date format. To convert a text in cell A1 to date, you just write =DATEVALUE(A1)

However, DATEVALUE formula has some limitations. It cannot process all types of dates. For eg. I have shown a few sample dates along with corresponding DATEVALUE output.

Using DATEVALUE formula to convert Text to Date

Readjusting Date Text so that it works with DATEVALUE formula

Whenever possible, your next best option is to re-adjust the source data text so that it can be understood by DATEVALUE formula. Here is an example.

Using Text formulas and DATEVALUE to convert Text to Date

We can use the text formulas like LEFT, RIGHT and MID to extract portions of the date text and then regroup them using & operator to create meaningful date text format that would be understood by DATEVALUE formula.

Technique 3: Using DATE formula to Convert Text to Dates

If your data has separate columns for date, month and year, you can use DATE formula to convert the data to dates like this:

=DATE(year,month,day)

For eg. =DATE(2009,12,31) will give the date 31st December, 2009.

Bonus Technique: Converting Dates to Text

If you want to convert excel dates to text values (for your report or some other purpose), you can use the TEXT formula like this:

=TEXT(A1,"DD-MMM-YYYY") will convert date in Cell A1 to DD-MMM-YYYY format. You can pass any other date / time formats to TEXT formula as well. [more: tutorials on TEXT() formula]

How do you deal with troublesome dates?

Of course, if it is a real date, we can always bolt. But if it is a date in the data, we need some tools to deal with it. I used to rely on formula based methods to clean the dates. But recently I discovered the import-text date conversion method. This is very powerful and straightforward. Now, I use it whenever possible to clean up my date data.

    This borders on Excel soft-cell...er, soft-core...porn. My favorite kind.

  2. Tim says:

    Wow, that is pimp-TASTIC! I have a question, as a VBA n00b: additional comment boxes stay plain unless I "run" the macro. Is there a way to change all comments, going-forward?

  3. laguerriere says:

    hi Chandoo, well, I like the macro approach. For those who don't like it, there is another way: just add the "draw" toolbar to the shapes toolbar (via Custom etc), click on "edit comment", click on the auto-shape and then choose "draw" drop-down, --> modify auto-shape --> then you even can have a heart or a banner (I like the horizontal banner in in purple :-)) . in excel 2007, you have to add this custom menu that you choose via Excel Options --> Custom --> it is called "change/ modify auto-shape"!!!
    best,

  4. Tom says:

    @Chandoo. Great Post 🙂
    @Tim : the way the macro is coded, it must be run very time.
    @Community: If someone has an idea to perform it when opening an existing excel, it should be nice.
    @Community: if someone has some code to revamp the commentboxes on all sheets, please share it. 🙂
    @Microsoft Excel-progammers: some pimpoptions for the commentboxes should be great.

    Cheerio

  5. Yukikomi says:

    For the auto run, please add the codes in workbook:

    Private Sub Workbook_SheetActivate(ByVal Sh As Object)

    Call Comments_Tom

    End Sub

  6. Debra says:

    Wow, that was a lot of fun... Thanks Tom!

  7. Chandoo says:

    @Jeff... Now, 5000 people know about your favorite porn... 😛

    @Tim ... you can write an event to handle the new comments. I wouldnt recommend it as it is really painful. another option is to use the macro suggested by Yukikomi. It will update comments everytime you activate the sheet.

    @laguerriere: very cool 🙂

  8. Johnnie says:

    @Chandoo ... Thanks! This is good stuff. I combined your tip with a tip from Mark O'Brien, then assigned it to a button on Excel 2010's Quick Access Toolbar, to format comments AS I add them. I also like how Mark's code saves me the trouble of backspacing my name out of new comments:

    Sub AppendToExistingComment()
    'Source: Mark O'Brien at http://www.mrexcel.com/forum/showthread.php?t=57296
    Dim oRange As Range
    Dim oComment As Comment
    Dim sText As String

    'Use object variable to hold range.
    Set oRange = ActiveCell
    'Use object variable for comment
    Set oComment = oRange.Comment
    'text to be added to the comment box
    sText = InputBox("Type text to be added:", "APPEND TO COMMENT TEXT")
    If Len(sText) = 0 Then End
    'If Active Cell has a comment then append new text to the end of the comment text
    If Not oComment Is Nothing Then
    sText = oComment.Text & vbNewLine & sText
    oRange.Comment.Delete
    End If

    'Add a comment with the contents of sText
    oRange.AddComment sText

    DoEvents
    Comments_Tom

    End Sub

  9. Nick says:

    Thank you very much for the code, it seems to be working for the most part; I am having a problem however. Once the routine makes the corrections to the comment, the comment becomes invisible. By invisible, I mean that when I highlight my mouse over it, nothing appears. However, when I right click the cell and click 'edit comment' then the comment becomes visible and I enter edit mode. Upon clicking out of the comment, it simply vanishes again. I've tried to fix this problem by adding a .shape.visible = msoTrue but then every comment is always visible. o_O please advise...

    Thank you,

    Nick

  10. Shailyog says:

    @Nick- That is because the font color of the comment is white and when you select the color of selection is also white hence you can not see anything. Try to change the color code in the routine to something else. would work

  11. Michael says:

    Thanks for that! The code works perfectly!

  13. Sunny says:

    @ Chandoo - code works great and the comments look super cool. But I have ran into a small issue. In the comments, I am inserting pictures. When I run the macro, for all comments which already have pictures; pictures are deleted. Pls help me retain the pics in comments.

  16. Deepak says:

    Hi Tom,

    This looks really excellent. I am however relatively new to macros / VBA codes so having copy pasted your code in the Developer mode of an Excel file, what are the next steps to use them? Can you please help? Just to recap, I opened a blank Excel workbook, clicked on Developer, copy pasted the comments code and saved the file to the desktop.

    Now how do I go about using it to add comments to an existing file? My apologies for asking a question which may be basic to you great geniuses, but I am not there yet and aspire to get there.

    Many thanks for helping me with next steps that I need to take so that I can now use the code.

    Best Wishes

    Dear Dave,

    The best thing to do is to copy the macro in the personal.xls(x) file. The personal excel file will always be launched when you open excel so you can use it with every excelworkbook.
    Read all about it on the page of Microsoft.
    https://support.office.com/en-us/article/Copy-your-macros-to-a-Personal-Macro-Workbook-aa439b90-f836-4381-97f0-6e4c3f5ee566

    Once you have the macro in the personal, you can 'call' the macro by the keyboardcombination 'alt+f8' and klik on the macroname.

    Hope this clarifies the 'how to'. Good luck with your first steps in the wonderfull world of macro's.
    Tom

      Hi Tom,

      Many thanks. I will try that out. Learning is fun and learning this stuff is even more amazing.

    There is a line 'Dim LArea As Long' which does not appear to be used. Have I missed something?

  19. Luis says:

    Excellent hack!
    For some reason when I opened my file after using LibreOffice Calc, all comment boxes had changed to some arrow shape.
    So this macro helped me from manually changing more than 5000 comments in a worksheet, or having to install some Excel extension.
    I used it with the following attributes to get back old style comments:

    It helped me from manually changing more than 5000 comments in a worksheet, or having to install some Excel extension.

    .Shape.AutoShapeType = msoShapeRectangle
    .Shape.TextFrame.Characters.Font.Name = "Calibri"
    .Shape.TextFrame.Characters.Font.Size = 10
    .Shape.TextFrame.AutoMargins = True
    .Shape.TextFrame.AutoSize = True

    Thanks a lot!

    But wanna remark on some general things, The site style is great,
    the articles is really great : D. Good job, cheers

  22. Jen says:

    Is there code to add to this that will format a particular part of the comment (i.e. make the last sentence in the comment bold and in italics)?

  23. Phil says:

    This is fantastic!
    How would I add auto-sizing to it?
    I tried adding this:
    .Shape.AutoSize = True but it gives me an error and as a novice at VBA I can't figure it out.

    This is GREAT!

    How should the code be changed in order to tun once for all worksheets in a workbook?
