The software format/vendor is immaterial. I concur with the above responses indicating that content is much more important than the file type. Some of the journals that accepted my work converted source files into pdf documents during the submission process. The pdf files were then sent to the editor and reviewers through the automated submission system. So, no, I don't believe the original tool used for writing the paper matter. However, content , adhering to the style format (APA, Chicago, etc.), and following the publisher's directions for submission are very important.
The content of your manuscript should matter rather than the type of software you use.
On the other hand, each of the journals have their own specifications including the format, font size, style, etc., in addition to acceptable word editing software.
If your submission conforms to these guidelines of the journal, and found worthy of publication, then nothing should matter.
After all, what do you want? to publish in a reputed journal or to insist on your specifications to the journal? The answer to this question answers your question.
I completely agree with what has been stated in the previous response. Each journal has its own guidelines. Check the website of the journal that you intend to submit your work. Guidelines for article submission normally stipulate in detail what an author needs to prepare before an article is submitted.
