Hi Kjell,
Thank you for using Syncfusion products.
We have tried the sample at our side for exporting the data to an excel file from the data table. We could see the Sewdish characters are exported without any problems.
We have attached the sample with this mail for your reference.
Please try the sample at your side and let us know if this helps you. If you still face the issue please get back to us with the simplified sample to proceed fruther on this.
Note:
We have check with our Essential Stuio 9.3.0.61, 9.4.0.62 and 10.1.0.44 and we are unbale to reproduce the issue.
Please let me know if you require any further clarifications.
Thanks,
Sridhar.S
