Hi Kelly,
Thank you for your interest in Essential DocIO.
Sorry for the delay in getting back to you. Essential DocIO can convert html strings into word document using HtmlToDls converter. I am afraid, currently we do not have any editors to create templates.
However, we can perform mailmerge and convert the convert the word document to PDF document.
Here is a sample for your reference.

Please let me know if you have any other queries.
Regards,
Dhivya
