Reply To: Exporting To HTML

Ajar make an export function called in5 which works very well. However at the moment they have a stone-age licensing system which means that when you activate your licence on your machine it is locked for ever – you cannot deactivate and move to another machine, you cannot move it to a different version of InDesign when Adobe changes CC again. So be warned before you invest!

I might add my HTML knowledge is limited to say the least, so it may not be a solution to your specific problem, but you never know. https://ajarproductions.com/pages/products/in5/
