I want to extract TEXT only from our InDesign file as HTML. In previous versions of InDesign, we could deselect the image option and would produce straight text. Turning off that option now in CC still sends the images to the HTML file.
You can use Articles Panel to achieve this. You can create article and only add text frames to it.
While exporting to HTML, select Content order as "Based On Articles Panel". This way, only the frames that you have added to articles will be part of HTML.
Please let me know if you need more clarity about this workaround.
