A small Python script to convert Diarium JSON export to the format I use in Obsidian

diarium.py

# Prereqs: pip install pendulum markdownify

import json
from string import Template

from markdownify import markdownify as md
import pendulum

with open("diary.json", "r") as file:
    data = json.loads(file.read())

for entry in data:
    date = pendulum.parse(entry.get('date'))

    location = entry.get('location', False)

    content = md(entry.get('html'))

    template = """# $date

<< [[Private/Journal/$prevdate|$prevdate]] | [[Private/Journal/$nextdate|$nextdate]] >>

$content#journal"""

    header = """---
journal: diary
journal-start-date: $date
journal-end-date: $date
journal-section: day
"""

    # I use MapView so retained location
    if location:
        header += f"""location: [$xloc,$yloc]
"""
    
    header += """---
"""

    template = header + template

    opts = {
        'content': content,
        'date': date.format("YYYY-MM-DD"),
        'prevdate': date.add(days=-1).format("YYYY-MM-DD"),
        'nextdate': date.add(days=1).format("YYYY-MM-DD")
    }

    if location:
        opts['xloc'] = location[0]
        opts['yloc'] = location[1]

    src = Template(template)
    result = src.substitute(opts)
    
    with open(f'journal/{date.format("YYYY-MM-DD")}.md', 'w') as file:
        file.write(result)

NOTE: I don't use this format currently but it's close enough
