Is there a way to strip special characters from {{value}} to prevent errors when used for a note's file name?

[ASalvail]

Title says it all. As an example, I just tried to type in a colon in my note, which prevented the file from being created. I would expect them to either be removed, or replaced by spaces, underscores, dashes, etc.

I suppose I could do use a snippet of javascript, but I figure that's something fairly common that people would like to do, so maybe I missed a feature?

Thanks in advance!

You didn't miss it, but it is a bit tucked away: format tokens take a |case: transform, and most of the styles strip characters that are invalid in file names, colons included. Enable File Name Format on the choice and set it to e.g.

{{VALUE|case:title}}

which keeps the same name prompt but turns Meeting: notes into Meeting Notes. The available styles are kebab, snake, camel, pascal, title, lower, upper, and slug (lowercase-dashed, and my pick for cross-platform-safe names). It composes with other options too, e.g. {{DATE:YYYY-MM-DD}}-{{VALUE:title|case:slug}}.

Two caveats:

• lower and upper only change letter casing; they don't strip anything. Use title, slug, kebab, or snake for sanitizing.
• There's currently no transform that only strips illegal characters while preserving your exact casing and punctuation - title re-cases each word and splits on boundaries like camelCase. If that matters for your titles, open a feature issue for a strip-only filter and I'll take a look.

Thanks a lot! I'll give title a try, it seems to be the closest to what I'm looking for.
