No. Insights → Transactions and the other Insights pages don't have an export. For payment data, export from your Stripe Dashboard. Nettla adds the club, booking dates, wallet use and line items to every Stripe payment.
Export payments from Stripe
Successful payments: see "How do I export successful payments from Stripe?".
Refunds: see "How do I export refunds from Stripe?".
Nettla's extra columns: see "What Nettla data is included in our Stripe export?".
What you can export from Nettla
Player list: go to Players → Player List and click the export icon, then Export all players (or Export selected players if you've ticked rows). You need the Can export player list permission, and it works on desktop only.
Membership data: go to Players → Memberships, click the export icon, choose Export membership data, set the From date and Until date, and click Export.
Send data automatically to other tools
Under Settings → Integrations, you can connect Google Sheets, BigQuery, Mixpanel, Zapier or a webhook to receive booking and payment data as it happens.
Good to know
Payments marked as paid, free of charge or paid only with a club wallet aren't in Stripe. Use Insights → Transactions or an integration to see them.
