When saving a document to Saved Templates, Advanced Document Automation will automatically set the name of the document to the name of the file that was uploaded. You can of course always change the name of the document by hovering over it in Saved Templates and clicking the pencil icon.
If the document's file name has any special characters in it (for example í or ö ), the add-in will encode the name of the uploaded document in the collection, such that it looks something like this: ZG9jLmRvY3g . This is due to restrictions on the allowed characters in the name of a document. If your document's filename contains special characters, you have two options:
Change the filename in Word to remove any special characters and save the document to Saved Templates once again.
Save the document to Saved Templates and edit the document's name after it has been saved there by hovering over it in Saved Templates and clicking the pencil icon.
If your template name doesn't include invalid characters and still receive this error message, most likely one of the folders/subfolders where this Word document is saved in your computer has an invalid character.
Click "File" on the top left of your screen, select "Properties" > Location to see your document's file path.
