I am receiving this error when i use the csv importer.

  • Unable to parse created date: 1/1/12 7:16
  • Unable to parse created date: 1/1/12 7:28
  • Unable to parse created date: 1/1/12 7:35
  • Unable to parse created date: 1/1/12 7:38
  • Unable to parse created date: 1/10/11 10:19

i have tried several date formats. yyyy/MM/dd h:mm a, yy/MM/dd h:mm a, MM/dd/yyyy h:mm a, and MM/dd/yy h:mm a

Any help would be appreciated. Thanks.

Have you tried the dates in full format with matching masks (your dates and masks as posted don't match at all)?

e.g. 30/02/2012 10:19 with a date mask of dd/MM/yyyy hh:mm

Nic, thanks for pointing that out. Excel was messing with the format of my dates. All is well now. thanks!

Hello Julian,

What exact chnages you have done in csv file. I have set the custom format as mentioned by Nic and upload it again. However I am getting the same warning.



No luck Dj.. getting the same error.

Hi Julian- what exactly did you try? i mean what changes you made in the excel csv format. what date format did you choose

Dear sir, 
I have exact the same problem and use exact the date mask but it's still failed. 

Do you have any idea to troubleshoot?


When importing, and your Jira format is: dd/MMM/yy h:mm a  

from an excel csv file, use custom format: dd/mmm/yy h:mm AM/PM

This works for

  • Date Created
  • Date Modified
  • Due Date

This worked for me; thank you!

THIS WORKED FOR ME! Thank you! A succinct and clear answer. I just wanted to upvote this comment so hopefully it gets more visibility.

Worked thank you! 

I have tried this (dd/MMM/yy hh:mm:ss a) format and its working without any error.

Arpita - Can you please try to change the format in excel and import the issues.

In CSV we can't edit the date format. To edit that open the CSV fiel in notepad++ & do the changes.

In your excel file, make sure you format the date field using use custom format: dd/mmm/yy h:mm AM/PM

Hi Nicole.. Thank you for getting back to me. I have done that as well. Quick question, will it be sufficient that the date displays as dd/mmm/yy h:mm am/pm or do i need to update the date itself? The custom format only changes how this is displayed rather modifying the actual data. Once i have some more guidance i can take another shot at uploading this data. 

That should be sufficient.   It works for me if you save the csv with that format for your date columns.

My workflows involves exporting the query results from workbench adn importing into excel to correct NULL values and bad description field entries. I save it from excel and import into Jira.


Can you let me know the date format configured in your Jira. Make sure you make the changes to Excel dates similar to it.

dd/MMM/yy h:mm a

Hi Arpita,

Please check the date format that has been configured in the System Info section and use the same. Also per Sateesh, make the same date format changes to CSV before importing. Hope it helps.

Hi Dhananjay, can you tell where exactly in the system infor section date format is mentioned.

Ensure your data format in CSV is tally with your JIRA date format ( System > Look & Feel > Scroll to the bottom ) before importing. As Excel usually messed with your date format.


By default it should be as below:

*dd/MMM/yy h:mm a*

YYYY-MM-dd HH:mm this is in my look and feel so i must use the same ?

Also Excel doesn't offer the date format of *dd/MMM/yy h:mm a* so whey wont' JIRA accept a standard format like mm/dd/yyyy h:mm a* ? So you're required to create your own custom format and apply it. Seems like a lot of overhead to import.

Hi I tried changing the format of the date in excel and my csv but still getting errors and incorrect dates when i do bulk uploads of issues. this is the error that I am getting. 

Unable to parse datetime: 24-Feb-20 using the date format pattern: dd-MMM-yy h:mm a


Anything that I am missing here?

Hi Robin,

Even i got the same error 
did you find any fix for it


In the CSV file, set the Custom format of the date column to "dd/MMM/yy h:mm AM/PM" and try importing it. It worked for me.

Like mittal.g likes this

Hi Sriram, Setting the custom format as stated works

I've had some issues with CSVs imports failing. I fixed them by:


- changing the delimiter in the csv to comma , in stead of (originally) semicolon ; or other delimiter

- setting date in csv to dd-MM-yyyy HH:mm e.g. 03-10-2020 14:41 (October 03 2020 2:41 PM)

- setting import config to dd-MM-yyyy HH:mm as well (same as in csv)


Example of contents of this in the csv:

Issue key,Summary,Created

KEY-123,Summary goes here,03-10-2020 14:41


When CSVs are provided, the date should be noted in the file as dd-MM-yyyy, but is sometimes noted as by original poster, with / between day/month/year.

Importing also works when using the MM-dd-yyyy format, e.g. 10-03-2020 for October 03 2020.

I followed below steps:

1). In my .csv file:
-> Snapshot of my .csv file:


->Right Click on 1/3/2020 13:31 -->Format Cells -->Custom--> m/d/yyyy h:mm
Then click on ok.


--> In my .csv file, the date-time format, I have opted is:m/d/yyyy h:mm

--> Jira setting -> System -> External System Import
     Kindly use date format in Jira Import: m/d/yyyy h:mm( Same one that you have used for your .csv file).
