Date change when writing to excel xlsx

Hi Community

This is OS/Excel regional settings conflict issue not PAD issue.

It is actually row 1 and 2 recognized as date.

Third row is not recognized by Excel as date but as txt

It seems your OS uses MM-dd-yyyy and you are passing dd-MM-yyyy.


Try reformatting your variables to match OS regional settings, otherwise you will need to format the Excel cells before you paste the values.

Hello @kriho 


I'll just post a dirty workaround.

Instead of using the "Write to Excel worksheet"-action, you could instead use the "Activate Cell in Excel Worksheet"-action and then use the "Send keys"-action (don't forget to add a {Return} at the end).
If you get the same problem as before, you may have to look at the cell format for those cells in particular, as momlo suggested.

Hi momlo

My OS uses dd-MM-yyyy

You can use "Convert datetime to text" action and save dates as text on excel, avoiding auto format by excel.FOrmat as text.png

Looks ok, I woudl only check in Excel if there is no setting overwriting default date.

Did you try reformatting your variables to see if this solves the issue?



Hi Momlo




No difference in saving from date to text and then writing to excel

I took more time and tested on my machine:


1. Regional settings matach yours: short date = dd.MM.yyyy



2. I assume based on your code, this is format you want to get in excel:




3. I recreated your code




4. And I got... the same result as you. But! We thought it is row 3 put incorrectly and rows 1 and 2 ok, but this is exactly opposite if we use formulas to grab parts of a date:




5. I did copy/paste the values from notepad and voila! Values are correct in Excel. So definitely issue between PAD and Excel




6. I have then reformatted variables in pad from your 'dd-MM-yyyy' to 'MM-dd-yyyy' and this time - correct results in Excel.






So to wrap up:

When pasting value from PAD (yours and mine) - values are assumed by Excel as 'MM-dd-yyyy' as suggested initially.

I try to avoid using pasting dates into Excel - afaik it is nightmare with those formats conflicts, so for example I often put time stamps as text.

Hi momlo thanks for the test

I am a little concerned about PAD assume that date is MM-dd-yyyy. Because what if the date already is MM-dd-yyyy will it not change it to dd-MM-yyyy.? 

When writing the date it should be that what you see is what you get and no change in format.


An example when you write a datatable using write to Excel worksheet and the dateformat is dd-MM-yyyy

is very convenient first to change the dateformat to MM-dd-yyyy in the datatable before using the action write to Excel worksheet.?





Writing to excel using datatable



date has changed.

The OS is dd-MM-yyyy

To me that should be an error. It is not logic to change the date format everytime you write to excel.?

Thanks @kriho 

I also found my solution by adding: ' in front of the text variable to insert as text into Excel.

My dates come from another excel file, which i needed to pass through if statements and then write back the resulting dates into Excel which created the issue in the first place.

Hello! Reading about the situation with dates, I'm also an RPA developer and use PAD. When I've wanted to work with Excel, the date format changes when using the Write to Excel Worksheet instruction.

Despite trying all the previously mentioned solutions, nothing worked.

Finally, I decided to use the instructions that allow creating a data table. This way, it's possible to retrieve and write Excel data without losing the date format.

I've attached an example image of what was done. (It might be a bit more complex, but it works to maintain the desired date format.)


I hope it is helpful. If you have any questions, feel free to write to me. 🙂

I've experienced the same issue in the past. Try setting the column type in Excel to text, I'm pretty sure this is how I resolved it.
