I took a word docx and placed in a InDesign document and exported to pub reflowable
The majority of the pub looks good except for a ton of spacing issues.
The spacing is correct in the .indd but it is NOT correct in the exported Epub.
I took a screenshot of the docx and the pub in Ibooks side by side and you can see the difference and the second screenshot is the .indd file where you can see the correct spacing is in the doc.
Any help as I do not want to manually edit this in an epub editor it is a large book.
Are you under the impression that you can just place a Word file into ID and then export it to EPUB with no work at all?
Unless you properly style all the text with paragraph and character styles (and tagging them), the chances of getting something that looks correct is very slim, IME.
No I understand that but when I first saw the incorrect spaces in the Epub and then saw the proper spaces in the .indd I figured it was an output setting that I had wrong.
You need to check the styles and map them to tags. Use classes if you need them and for special cases write your own CSS and link to it.
