I checked out what you get when you export your content from Twitter, Facebook, Google+, LinkedIn, WordPress and LiveJournal, with an eye for both private archives and migrating to your own site.
Tired of Twitter? Fed up with Facebook? Irritated by Instagram?
If you want to leave a major social network, but keep your content — or even just make sure you have your own backup in case the site shuts down, purges accounts, or changes its TOS *cough* LiveJournal *cough*, you can usually get some of your info. But not all of them give it to you in a way that’s useful.
You get a CSV spreadsheet containing all your tweets since the dawn of Twitter, with the text in one column, ID in another, timestamp, reply-to, and so on. It’s pretty easy to import this into another system. (I pulled mine into a test WordPress site using the WP All-Import plugin.)
Links in the text appear as the t.co shortened URL, with the “real” URL in another column. Of course, if the “real” URL was also a shortener, you’ll just see bit.ly or whatever. And if you’ve been on Twitter long enough, you may find that some of your older links use shorteners that don’t exist anymore (or have purged their archives), like ping.fm or tr.im.
You also get an offline web app with an index.html that allows you to view all your tweets month by month without visiting the site.
But you don’t get any of your uploaded media, or direct messages. So if you mostly use Twitter for text-based microblogging, you’re fine, but if you use it for photo sharing or private conversations, you’re out of luck.
Update: Retweets are sometimes incomplete in the spreadsheet. The text field is a constructed manual retweet — “RT @otheruser: Text of the original tweet” — but it’s truncated to fit in 140 characters (even if the original was made after the 280-character update). So if adding the username pushes it over the limit, or if it was longer to begin with, you don’t actually get the entire original tweet in the spreadsheet. I suspect this means retweets don’t actually use that field, and get the content straight from the original tweet by ID.
You get all your photos, videos and messages, organized by folders, but the names are all just numeric IDs. You do get an offline web application that includes names and indexes.
It also has your entire timeline in one giant HTML file. But it only includes the text, the type of update, and the timestamps. If you posted a link, it doesn’t include the link. If you posted a photo, it doesn’t link to the photo.
And you don’t get comments, either your comments on other people’s posts, or their comments on yours.
Worst, though? It doesn’t indicate the privacy of each post. That means you can’t take the timeline and import it to a new system unless you separate the public and private posts one by one.
Google Takeout allows you to export various categories of data, including your Google+ stream, circles, +1s and page posts.
Each post is exported as a separate HTML file, named after the first line. Comment threads are included, along with timestamps, a permalink to the original post, and a visibility indicator. It only marks Public vs. Limited, but that’s better than you get from Facebook.
The HTML files are suitable for publishing as-is, and marked up so that that it shouldn’t be hard to write an import tool for a CMS. (I’m planning on writing a script to convert them to WordPress’ XML format.)
Images aren’t included in the G+ stream download, and are instead hotlinked on photo posts and galleries. I haven’t checked, but I suspect any images you uploaded to Google+ will be included in your Google Photos download.
There is an index of all your posts…but it’s in alphabetical order.
Bonus: Google Buzz
When Google shut down Buzz a few years ago, they generated archives and put them in each person’s Drive account. They did one cool thing, which was to create two sets of archives: One complete, the other containing only public posts.
The format? Long PDFs, dozens of pages each, with all your posts, labeled by source (Buzz, Twitter, a specific site, etc.)…with the letters scrambled. Apparently they left the “reduce file size” option turned on when they generated them. This means you can’t copy/paste or search in the PDF itself, but you can open it in Google Docs and it’ll convert the text back, at which point you can do both. But that doesn’t preserve links or media, which you have to get out of the original PDF…
LinkedIn generates two phases of archives. The first one, available within minutes of requesting it, contains your profile info, your messages, contacts and invitations in CSV files.
The complete archive, available within 24 hours, actually lives up to the name. Everything is in a set of CSV files: Your contacts, your shares, your group posts, your group comments, even your behind the scenes info like ad targeting categories and recent login records. (One word of warning: They’re encoded as UTF-16, so if the tool you use to import afterward isn’t expecting that, you may need to convert it.)
I’m not sure how photos and video are handled, as I’ve never uploaded either to LinkedIn (other than my profile picture, which landed in a folder called Media Files).
LiveJournal’s own export tool will export a month at a time into a CSV or XML file, which includes your posts and their metadata (timestamps, moods, etc.), but not comments, userpics or photos.
There are other tools available using the API, which might be able to get more data. I’ve looked at two:
The WordPress importer will pull in all your posts, and the comments on them, and makes a note of moods, music, etc. (you can use my LJ-Moods plugin to display them). It doesn’t transfer any images you’ve uploaded.
DreamWidth’s importer seems more complete – LJ and Dreamwidth are based on the same code, after all – and is able to natively handle moods, userpics, etc. But it doesn’t transfer your media library either.
WordPress exports a giant XML file containing all your posts, their comments, and their metadata. You can import it into another WordPress instance, and have virtually the same blog. Or you can merge two blogs together by importing both. (I’ve moved posts with comment threads from one blog to another by putting them in a category, exporting the category, and then importing them on the new blog.)
It doesn’t include your media library, but if you import the file to a new site before closing down the old one, the importer should offer to pull in all of the images and other media that are actually used in posts.
Plus on a self-hosted site you have a lot of tools available: backup plugins that will include everything, SFTP access through your web host, etc.
I didn’t initially include Tumblr because it doesn’t have an exporter…but WordPress has an importer that does a good job of transferring your blog directly from Tumblr to a WordPress blog. (Look on your WordPress dashboard under Tools/Import.) It even imports images (though sometimes it imports a single-image post as a gallery for some reason). The original URL is stored in a custom field, and you can leave it connected and import new items when you want to bring them in.
Some gotchas: It can only map to one author, but you get to choose which one. It puts everything in the default category. Videos don’t get imported, even if you’ve just embedded a YouTube video.
Instagram doesn’t have an export tool, so you have to rely on third-party solutions.
Flickr allows you to bulk-download photos from your Camera Roll, and it helpfully uses the title to name the files, but it doesn’t export the description, tags, or comments.
Mastodon currently only lets you export your contacts and block lists, but archiving and migration (from one Mastodon instance to another) are on the roadmap.
