Conversion of docx files with Mathtype equations is not done properly (by Uploading docx to docx2Latex website)
There are some ways to fix this:
I have written a macro which converts Mathtype equations to MS word equations, then we can use Doc2Latex for conversion to Latex: https://github.com/aminya/Amin-MSWord-VBA-macros#mathtype2word
Another way is to convert Mathtype equations to Latex inside MS word (Mathtype has a macro for this). But Doc2Latex should have some logic to detect the equations that are between
$ $, and not convert them to simple text, and instead to math equations. In Google doc addon, the user can inter Latex blocks for these, but it is time-consuming and manual.
Fix the direct conversion errors.
Now without any change Mathtype equations like this:
are converted to this:
Also, equations numbers are ignored which is another problem!
