Local-only analysis
Paid vs. free subscribers, revenue trends, and issue performance — built from your own exports, no live API required.
Step 1
Import your exports
Substack export (.zip or CSV files)
Expected columns: posts.csv, delivers, opens, email_list.csv
Settings → Import/Export → Create new export. Open rate is calculated from the delivers/opens files — it isn't a column in the export.
Drag & drop the export .zip (or its .csv files) here
Stripe payments CSV
Expected columns: date, amount, status
Not part of the Substack export — Stripe Dashboard → Payments → Export. Without it, revenue metrics stay hidden.
Drag & drop a .csv file here
