Depending on how many and what packages you use, the success of latex2rtf can be somewhat disappointing. After many trials, I have found UniPDF, a software free of use for private use. Might be worth a try.
It is, of course, not perfect, however images and tables to some extent are converted quite well, while formulae only if they are not too complex. What is much better compared to other converters from PDF to doc format is that most individual lines are not converted into single paragraphs, but correctly into actual lines.
I agree with Partha Sarathi Chakraborty . I converted my Latex pdf file to word through the website mentioned by Mr. Chakraborty ( https://pdf2doc.com/). It is very convenient. Thank you.
I think Hard, Elements in Latex are not the same in Microsoft Word , but you can from Latex to PDF , then PDF to Images, there is some websites or Apps can convert from Picture to Text that you can copy/paste it,
Since pdf2doc has been mentioned quite often I tried it and compared it to my favourite converter UniPDF (https://unipdf.com). Since both delivered the same result and made exactly the same mistakes at the same spots it seems that the underlying algorithm is very similar to say the least.
Thought that this might be interesting for anyone who for various reasons does not want to upload her/his files.
Abderrahim Zagane : There would probably be a sufficient number of answers for its own thread! To start out, there are several online services, that claim to convert your word file flawlessly.
It has been a while since I made use of them, however, I had some fairly good results with the two plugins for the Word (https://www.wordtolatex.com/) and Libre/OpenOffice (http://writer2latex.sourceforge.net/) with the latter accomplishing better results, since it is less tricky to use and also converts (basic) figures into tikz-graphics. The procedure is the same for both: you install the plug-in, open your word-file as usual in Word or LibreOffice, look for the option to export/save the file to/as tex and the rest should be taken care of according to your settings.
Of course, you should not expect a perfect conversion since many of the trickier things require manual tweaking, but you will receive a solid tex-document to start with!
