Your financial data, anywhere you need it.

MAX unlocks the CLI and REST API — sync transactions to Postgres, SQLite, CSV, or any database, directly from your terminal or application.

CLI

Pipe transactions to any destination from your terminal. Cron it. Script it. Own it.

Any destination

Postgres, SQLite, CSV, or JSON. Standard SQL schema, ready to query.

REST API

Full API access with your MAX API key. Build custom integrations, dashboards, or automations.

Sync to anywhere.

One command. Your transactions in any format, any destination.

Postgres

sheetlink sync --output postgres://localhost/mydb

Upsert to sheetlink_transactions and sheetlink_accounts. Standard SQL schema. Query with anything.

SQLite

sheetlink sync --output sqlite:///~/finance.db

Local database. No server. Perfect for personal dashboards or offline analysis.

CSV

sheetlink sync --output csv

Flat file snapshot. Import anywhere. Default path ./sheetlink-transactions.csv.

JSON

sheetlink sync

Structured JSON to stdout. Pipe to jq, pandas, or any data pipeline.

Built for automation.

Real workflows that SheetLink CLI enables out of the box.

Nightly cron sync

Set it and forget it. Use a MAX API key that never expires, cron it to run at 2am, wake up to fresh data every morning.
