Guides

Step-by-step instructions for requesting your data export from each service, understanding the file, and getting the most out of the analyzer.

Choose your service

Every guide below covers three things: where to request your export, what is inside the file, and what the analyzer can and cannot tell you from it.

Amazon order history analyzer — request “Your Orders”, read Retail.OrderHistory.1.csv, and see spending by year, re-orders and price swings.
Not covered: digital purchases (Kindle, Prime Video, apps) and refunds, which Amazon ships in separate files.

Netflix viewing history analyzer — request your data download, open ViewingActivity.csv, and see total hours watched, top shows, binge days and a weekday × hour heatmap.

Spotify listening history analyzer — request extended streaming history, open the Streaming_History JSON, and see hours, top artists, skip rate and any single year.

YouTube watch history analyzer — export history from Google Takeout as JSON, open watch-history.json, and see top channels, Shorts share and rewatches.

Check who doesn't follow you back — export “Followers and following” as JSON, then compare followers_1.json with following.json locally. No password, no app.

Find recurring charges in a bank CSV — export your transactions as CSV and detect subscriptions, repeating charges, yearly cost, price increases and stopped payments.

Where to request your data — official “download your data” links for Amazon, Netflix, Spotify, Google, Instagram, Facebook, X, LinkedIn, Reddit, Apple and more, with what each export contains.
