Create Apple Shortcut to Import Day One JSON to Apple Journal

Description

I’m looking for someone to create a custom Apple Shortcut that can import entries from a Day One journal export into Apple Journal on macOS.
I have approximately 3,000 entries exported in JSON format using Day One’s native exporter. This export contains:
- A single Journal.json file with all entries (each including text, creationDate, optional location, and attached media references)- A /photos folder containing images, where each filename is based on an md5 hash found in the JSON- Optional /videos and /audios folders (support for these is a nice-to-have, not essential)
The Shortcut must:
- Parse the Journal.json file and loop through each entry- Extract the correct title, body text, date, and location info- Match and attach the corresponding image(s) from the /photos folder by md5 filename- Create a new Apple Journal entry for each, including date, text, photo, and geolocation- Handle missing fields gracefully (e.g. entries without a photo or location)
I can provide an example of how the data is structured in the Day One JSON export.
The Shortcut should be efficient enough to handle thousands of entries without failure.
This is a one-time job. I expect it to be straightforward for someone familiar with Apple Shortcuts and JSON handling on macOS.
