How Do I Make a Photo Book From a Google Takeout Export?
Fix the dates first. Photo book tools lay pages out in date order, and a raw export has no dates.
Photo book software arranges pages by date. Feed it a raw Takeout export and every photo claims to be from today, so the automatic layout is meaningless and you place hundreds of pictures by hand.
Fix the dates first and the software does the hard part: a chronological book, with the holiday in the right chapter.
Takeout JSON Metadata Fixer writes the real dates back into the files before you upload them anywhere. It runs on your own computer and is free for your first 500 photos.
