How to add multiple media files in a single question (using media::image, media::audio columns)

@BrunoAngelo

I would like to have a form already filled out but using the xml in a way that I can upload the file in the application with some questions already answered and others not..

Do you mean a default answer to a question? You can use default to set static or dynamic prefilled answers for the form this way

@BrunoAngelo

how do I convert this XLS to XML so I can import it to the app?

I upload my XLSX forms to ODK Central, which validates and converts to XML, I don't know what your configuration is, but there are online and offline methods to convert to XML XForms, (another)

is this ODK service Central, paid or free?
