I've only ever visited these forums once, and that was when I was trying to export my data from Evernote to a format that I thought I could work with properly. All the options/suggestions that have been provided on this site and on others were third party apps/ programs and needed payment to export the amount of notes that I had (I had 250+).
I ended up finding an article about LibreOffice (which I already had; its FOSS); it had the ability to convert to different formats from the windows command prompt, and with some extra code, it can all be done automatically in a batch from one directory.
So I thought I would provide a summary of what I did here; as this was the first place I looked (it appeared first after a google search).
1. I exported the files as html files (notes separated, not one whole html file) from the Evernote desktop application
2. I created a .bat file (write batch code in a text file then save it with the .bat extension) (I can't attach .bat files on this forum, sorry)
and ran the .bat file
The .bat file I created, converted all the html files to .rtf (rich text format) and I've stored all the different notes on my home server that I sync with Bittorrent Sync. It's easily changed to convert it to other files, but please beware that the html file may not create the play well with the format you're conveting it too and you may need to edit the end result, so that it will look the way you want. But, as for just storing the information that you have saved in Evernote, saving my files as .rtf was perfect and this way is free and can be tailored to different needs.
Below is the code of the .bat file I used, I had to implement a waiting period of 3 seconds, so that all the notes would be converted over in a batch automatically. I'm happy to answer any questions. HTH
REM This displays the files being converted in the command window
REM This changes the working directory to the location of the original files
cd "<location of original files>"
REM You can change the 'rtf' to 'doc' 'docx' 'odf' .. whatever you like.. as long as LibreOffice can handle it
REM Make sure leave the quotes "" when you replace the pointy brackets with YOUR directories that corresponds to the description.
