Change font family only via a script

[martinj54220288]

Hi 

Is there a way to a launch a script to automatic change all the paragraph styles in a file from one font family to another. 

I'd like to: open a indesign file, open scripts, click a script, choose a font family i want to change to (or have one assigned), then done? 

I dont want to change the font (i.e. bold, regualr, semi, etc), i only want the family to change. I can do this manually style by style but its a long process. I found this is the default change when i try to use the find and replace formatting option in indesign. 
For example i have english files in one font (Inter) and we have translations made for me but they require to to be in (Noto Sans SC) for Chinese. 

Thanks

I'm on my phone but hopefully it will work: 

app.activeDocument.paragraphStyles.everyItem().appliedFont = "name of your font";

It won't change Styles in subfolders - you can try and change it to allParagraphStyles.

Thanks, i have no experience writing scripts? Are you able to share a file so i can add to indesign or send an example how i can save the file locally.

Thanks on the upload scripts "how to". was able to add. Bookmarked for next time. 

I receive:

Error number 25?

Error String: Expected: ;

Should be "NotoSans SC" - inside double quotation marks.

Sorry.... still getting the same error 😞

Can you post a screenshot of your script - in a Notepad / text editor - with hidden characters visible?

Last error message should be rather clear - you forgot about the space after "Noto".

Wow, Robert, I can certainly use this too. Will this change the fonts in the Paragraph Styles descriptions as well, or is that too much to hope for?

What do you mean by "descriptions"?

[Susan Culligan]

Where you set up the Paragraph Styles. Maybe I'm using the wrong term, but the "helpful boxes" (as my ex used to call them) where you set up font, spacing, etc.

Can you post some screenshot(s) and mark a field(s) you're referring to? 

[Susan Culligan]

I see the screenshot where you check the box "Redefine style when changing all." That's exactly whe I needed.

Thanks!!!

Wi6thout a scrip you can use the command

Type > Dind / Replace Fonts …

Activate the option to redefine styles

I tthink it is better than a script as you see really all used fonts.

[Robert at ID-Tasker]

Or in Package.

[Willi Adelberger]

But with package you cannot redefine styles.

My screenshot says otherwise?
