Under windows, If note title contains / it will result in an error. BTW I suppose also : and + are forbidden character for Windows filenames

Example of offending file

{
    "color": "DEFAULT",
    "isTrashed": false,
    "isPinned": false,
    "isArchived": false,
    "textContent": "toto pipo",
    "title": "1: 12/3/24 ",
    "userEditedTimestampUsec": 1548706696486000,
    "createdTimestampUsec": 1548706676397000
}

Error

Hi Erik,

very much thanks for your script to convert HTML to MD and even adding the attached photos worked for me
They are displayed in the Nextcloud Web App in e.g. Brave Browser
allow me just a question, I am not requesting you to fix anything

Did you manage to use an Android App for watching Notes with Attachments?
The Nextcloud Android App and the Nextcloud Notes Android App cannot follow the link ressources/.... for the image tag in MD.

Thank you for your inspiriation and time.

After the conversion I noticed I was missing around 115 notes and it seems like notes with an identical name get overwritten, google keep takeout names the files as XXXX, XXXX (1) and XXXX (2), so I think this would be solved if your script uses the file name rather than the title from the json, would it be possible to change this?

Edit: The file with the largest number is the final "surviving" one

Get the error when it tries to convert, which to me indicates the colons need sanitized out
