Thanks for this useful script.

This small change sets the file modification time so it matches the original Google file. I find this helpful as then the Notes app can sort by date.

Line 5:

from os import listdir, path, mkdir, utime

Insert at line 153:

# use the original modification time for the new file original_mod_time = path.getmtime(path.join(keep_dir, note_file)) utime(path.join(nextcloud_dir, path_name, fname), (original_mod_time, original_mod_time))

You're welcome, thanks for the suggestion i'll make it right now

The utime call needs to follow the f.close() statement. Otherwise, the close call will update the modification time to the current time. :)

man, there's a lot of time that I don't put my hands on this, can you send me an example for me to update the script?

does anyone have an idea how to extend this ingenious script so that the german umlauts (ä, ö, ü, ß) are converted correctly?

EDIT: ok it was easier than I thought

Line 77:

From: note = to_dict(open(path.join(keep_dir, note_file)).read())
to this: note = to_dict(open(path.join(keep_dir, note_file), encoding='utf-8').read())

updated line 77 as @Expello mentioned
