Hi Reinaldo,
Thank you for contacting Syncfusion support.
We have checked your reported issue and we would let you know that we would suggest you to use the FromForm property as like as below, for save action to resolve this issue in your end. For your convenience, we have prepared the sample that refer the CORE WEB API. Please find the below links.

[HttpPost]
[Route("Open")]
public IActionResult Open(IFormCollection openRequest)
{
OpenRequest open = new OpenRequest();
open.File = openRequest.Files[0];
return Content(Workbook.Open(open));
}
[Route("Save")]
public IActionResult Save([FromForm]SaveSettings saveSettings)
{
return Workbook.Save(saveSettings);
} |
Note: launch the service first and then open the stack blitz sample for open/save action.
Could you please check the above details and get back to us, if you need any further assistance on this.
Regards,
Sangeetha M
