Is it possible to use a Handlebars helper to validate the Length of the string, in a smartdocs template

Hi Team,

As per the comment from https://community.apigee.com/questions/42144/handlebarsregisterhelper-smartdocs-template.html we can not register Handlebar helpers. I would like to check the length of string from list of my parameter names which I have is huge. Do we have any solution to overcome?

Regards,

Veera
