Spent a couple of hours converting my old posts from XML with custom schema to JSON. Scrubbed some obvious spam comments (any comment with more than 5 hyperlinks).
Result is a 7MB JSON file containing 1756 blog posts with comments. Hash of IP addresses were not archived so they’ll all be treated as self-proclaimed foobars.
Next step is to POST them as well as assets they reference to WordPress.com via REST API which should take another couple of hours of hacking since I haven’t bothered to convert the posts to RSS.
