Have you ever imported data into Excel, from your credit card statement, or somewhere else, and found that Excel dates won’t change format? And, if you try to sort that column of dates, things end up in the wrong order.
That happened to me this week, and here’s how I fixed the problem, using a built-in Excel tool.
Fix Dates That Won’t Change Format
This video shows how to fix the dates that won’t change format, and there are written steps below.
Dates As Text
In the screen shot below, you can see the column of imported dates, which show the date and time. I didn’t want the times showing, but when I tried to format the column as Short Date, nothing happened – the dates stayed the same.

Why won’t the dates change format? Even though they look like dates, Excel sees them as text, and Excel can’t apply number formatting to text.
There are a few signs that the cell contents are being treated as text:
- The dates are left-aligned
- There is an apostrophe at the start of the date (visible in the formula bar)
- If two or more dates are selected, the Quick Calc in the Status Bar only shows Count, not Numerical Count or Sum.

Fix the Dates
If you want to sort the dates, or change their format, you’ll have to convert them to numbers – that’s how Excel stores valid dates.
Sometimes, you can fix the dates by copying a blank cell, then selecting the date cells, and using Paste Special > Add to change them to real dates. There’s a video at the end of this article, that shows how to do that.
Unfortunately, that technique didn’t work on this data, probably because of the extra spaces. You could go to each cell, and remove the apostrophe, but that could take quite a while, if you have more than a few dates to fix.
A much quicker way is to use the Text to Columns feature, and let Excel do the work for you:
- Select the cells that contain the dates
- On the Excel Ribbon, click the Data tab
- Click Text to Columns

In Step 1, select Delimited, and click Next

- In Step 2, select Space as the delimiter, and the preview pane should show the dates divided into columns.
- Click Next

In Step 3, you can set the data type for each column:
- In the preview pane, click on the date column, and select Date
- In the Date drop down, choose the date format that your dates are currently displayed in. In this example, the dates show month/day/year, so I’ve selected MDY.

- Select each of the remaining columns, and set it as “Do not import column (skip)”

- Click Finish, to convert the text dates to real dates.
Format the Dates
Now that the dates have been converted to real dates (stored as numbers), you can format them with the Number Format commands.
There are a few signs that the cell contents are now being recognized as real dates (numbers):
- The dates are right-aligned
- There is no apostrophe at the start of the date (visible in the formula bar)
- If two or more dates are selected, the Quick Calc in the Status Bar shows Count, Numerical Count and Sum.

To format the dates, select them, and use the quick Number formats on the Excel Ribbon, or click the dialog launcher, to see more formats.

Everything should work correctly, after you have converted the text dates to real dates.

How to Fix Excel Dates That Won’t Change Format

___________________________
I recently upgraded from an old OS to a new Mac mini and all new software. Having used EXCEL for decades I am totally confused but the new software. In the process of working an old but revised spreadsheet, a big one, and found the date column had been changed to a number. the proper date is in the cells as shown in the formula bar, but I have failed to find a way to revert to the date format. This is limited to this one spread sheet.
Sounds simple but everything i have tried, for the last 3 hours doesn’t work. It used to be simple in the old version.
Any suggestions?
Thanks Debra, this was a real life saver!
Utterly amazing. You would NOT believe how many different (wrong) methods posted on the internet I’ve tried so far. This one worked perfectly (in Excel 2007). Where can I send you a monetary token of my appreciation lol?
So helpful ! Thanks !
my issue is when I type a date, it comes out in date format but an entirely different date than I typed. Example: when I type 1292014 it comes out 5/30/5437. Anyone know how to fix this?
Your computer actually stores dates internally in the Julian Date format. May 30, 5437 is stored as 1292014. If you type that number with either / or – between the day, month and year, it will read it as a date and format it as we humans recognize dates. {1/29/2014 or 12/9/2014} If you type in 1/29/2014 and change the formatting back to a number, it will give you the Julian equivalent of 41668.
This is brilliant! Thanks! I have been struggling for a while with a very similar case! Cheers. P.
