Hi again, today suddenly a bunch of users people started getting these errors while opening Excel files in the browser:
at C:WindowsTEMPExcel ServerFileCachefa812204-b6ff-40ec-9209-fe8add3de89eRanges. Excel Services Application is unable to function without a workbook cache.
Thanks to below links, issue could be resolved

Error:
Unable to create or access workbook cache at C:WINDOWSTEMPExcel ServerFileCacheSharedServices1-1078443246Ranges. Excel Services is unable to function without a workbook cache. (you can see this error in Event viewer)
Reason:
Unknowingly you may have deleted the above mentioned folders. So, Excel services is not able to save the temporary files under the “Ranges” folder.
Solution:
Login inside the SharePoint server and create the “Ranges” folder as per the above mentioned folder structure. If you are not able to see the “Excel Server” folder inside “C:WindowsTemp” folder, just create it manually.
hope it helps!
