Label description and visual markings character limitation

Occasional Visitor

Hi all,


Does anyone know if there is a limitation on how many characters a description and a visual marking (footer text for example) may have and if yes, what's the limitation?


With kind regards,

Have you tried in the Azure portal to see how many characters you can enter for these? I know they put max length validation in, so try there to confirm the maximum string length. But for the label descriptions, I think I remember it being 1,000 characters.

Actually, I've just documented this here as a new entry in the "additional information" list for visual markings, because we discovered Excel has a much shorter max string length for headers/footers (253 characters) - so the string can truncate if the number of characters that you specify for the label exceeds this number.  


To answer your original question:

  • Max number of characters you can specify for headers/footers: 1024
  • Max number of characters you can specify for watermarks: 255
