Incorrect date format in Excel when refreshing Excel Dynamic report (on one computer)

(2) ShareShare
ReportReport
Posted on by kazuma6666 11
Hello,
 
I'm the IT support and data analyst in my company. I have an issue with the new computer of one of my users. Whenever she refreshes a report, it shows incorrect dates. The dates are not recognized in excel, and they show as a very long number. 
When I refresh the report on my computer it works correctly, the dates are recognized again. As soon as I try to refresh again on her computer, the dates are incorrect again.
When we export the report for the first time it works correctly on her computer. As soon as we do a refresh, that's when the problem happens.
 
I had this issue in the past, and I think it was linked to regional settings or something similar. But I have compared the regional settings on my computer and this user's computer, and it seems everything is the same.
 
Any idea where this could come from? 
 
Thanks in advance,
Benjamin.

    Incorrect date format in Excel when refreshing Excel Dynamic report (on one computer)
    Hello Benjamin,
     

    You're right, this date formatting issue in Excel after refreshing a Dynamics 365 report is almost certainly related to regional settings, even if they appear identical at first glance. The devil is in the details! Here's a breakdown of troubleshooting steps:

    1. Excel Regional Settings (Most Likely Culprit):

    • Number Formatting: While you checked the general regional settings, pay close attention to the number formatting within Excel itself. Even if the system regional settings are the same, Excel can have its own settings.

      • Open Excel.
      • Go to File > Options > Advanced.
      • Click "Edit Custom Lists..." (under the "Web Options" section).
      • Check if there's any custom list that might be interfering with date recognition.
      • Go to File > Options > Advanced.
      • Look for the "Lotus 1-2-3 Transition" section. If the "Transition navigation keys" box is checked, it can sometimes cause date issues. Uncheck it

    • Date Formatting: Even if the displayed date format looks correct, the underlying format might be different.

      • Select the date column(s) in Excel.
      • Right-click and choose "Format Cells..."
      • Go to the "Number" tab.
      • Select "Date."
      • Carefully compare the exact date format selected here with the format on your computer. Even a slight difference (e.g., dd/mm/yyyy vs. mm/dd/yyyy) can cause problems. Try setting it to a standard format (e.g., yyyy-mm-dd) to test.
    • Language Settings in Excel:

      • Go to File > Options > Language.
      • Ensure the "Choose Display and Help Languages" and "Choose Editing Languages" are consistent with your settings.

        •  

    2. Dynamics 365 Regional Settings (Double-Check):

    • User Settings: In Dynamics 365, go to the user's personal settings (gear icon -> Personal Settings). Specifically check the "Format" tab. Make absolutely sure the date and time formats are identical to yours.

    • Organization Settings (Less Likely): While less common, the organization-level regional settings could be a factor. Check these settings in Advanced Settings -> Administration -> System Settings -> General tab.

      •  

    3. Browser Settings (Worth a Look):

    • Browser Language: While less likely than Excel settings, the user's browser language might influence how Excel interprets the data. Check the browser's language preferences.

      •  

    4. Excel Add-ins (Possible Interference):

    • Disable Add-ins: Temporarily disable any Excel add-ins the user has installed. Sometimes, add-ins can interfere with data interpretation.

      •  

    5. File Corruption (Less Likely):

    • New Excel File: Try exporting the report to a brand new Excel file on the user's computer to rule out any corruption in the existing file.

      •  

    6. User Profile Corruption (Rare):

    • New User Profile (Test): In very rare cases, a corrupted user profile can cause strange behavior. As a last resort, you could temporarily create a new Windows user profile on the computer and see if the issue persists.

      •  

    7. Dynamics 365 Report Settings (Check):

    • Report Formatting: Review the report's design in Dynamics 365. While less likely since it works initially, check if there are any specific formatting options set for the date fields in the report itself.

      •  

    Troubleshooting Steps:

    1. Focus on Excel: Start with the Excel regional and language settings. The "Format Cells" option is crucial for comparing the underlying date format.
    2. Isolate the Problem: Try exporting a very small subset of data from the report to Excel to see if the issue still occurs. This will help you rule out any data-specific problems.
    3. Compare Settings Meticulously: Even if the settings look the same, compare them character by character. A single space or a different separator can cause issues.
    4. Test with a Standard Format: Setting the Excel date format to yyyy-mm-dd (a standard, unambiguous format) is a good way to test if the problem is with date recognition or just display.

    Incorrect date format in Excel when refreshing Excel Dynamic report (on one computer)
    Indeed, but it is linked to dynamics. I am trying to get reports to work, and they don't. It seems to me this is the correct place to ask about this.
    I'm pretty sure if I ask this on windows forums, no one will know what I'm talking about.
     
    Kind regards,
    Benjamin.

    Hi, this issue does not seem to be with Dynamics, more of a local environment issue.
