I'm guessing from reading the forum, there is no way to create a file and save it to the client's pc using system.perspective.download.

I have a page that allows the user to set a bunch of settings and I was hoping the user could click an export button to save a json file locally. Is the only way to do this to use vision?

I was thinking I could maybe open a browser and dump the json into that so they could copy/paste the text but that's a bit wonky.

Anyone have any tips or suggestions? Thanks

`system.perspective.download()` causes the browser to open a save file dialog if the user has configured their browser to always ask for where to save.

Teach you users to set their browsers that way. Or use Vision.

Thanks, I have my browser (firefox) to ask where to save the file. I get prompted but when I select a folder nothing gets downloaded. I tried chrome and edge and got the same thing.

I don't see any errors or warnings from the browser. im just putting my json variable into the function, do I need to convert he json to bytes or anything?

Thanks!

JSON isn't one of the supported types for the `data` argument, so yes:

[system.perspective.download()](https://www.docs.inductiveautomation.com/docs/8.1/appendix/scripting-functions/system-perspective/system-perspective-download)

You probably want to run your json dictionary through [system.util.jsonEncode()](https://www.docs.inductiveautomation.com/docs/8.1/appendix/scripting-functions/system-util/system-util-jsonEncode)

Its a simple script, thanks!

```python
data = {'name':{1:1,2:1,etc...}}
system.perspective.download('download_me.json', data)

```

Awesome, thank you! I didn't know there were unsupported types, I was assuming it would come across as a string but I didn't print the type to find out.

It worked, thank you!
