I think this applies to your case, taken from here → [GPL FAQ](https://www.gnu.org/licenses/gpl-faq.html#WhatCaseIsOutputGPL)

**In what cases is the output of a GPL program covered by the GPL too? ([#WhatCaseIsOutputGPL](https://www.gnu.org/licenses/gpl-faq.html#WhatCaseIsOutputGPL))**

_The output of a program is not, in general, covered by the copyright on the code of the program. So the license of the code of the program does not apply to the output, whether you pipe it into a file, make a screenshot, screencast, or video._

_The exception would be when the program displays a full screen of text and/or art that comes from the program. Then the copyright on that text and/or art covers the output. Programs that output audio, such as video games, would also fit into this exception._  
…

Since you say the users will be only be interacting with the output like documentation and data sheets, the output itself is not GPL unless you are including the code with it.
