Sync to anywhere.

One command. Your transactions where your tools already look.

Upserts into sheetlink_transactions and sheetlink_accounts. Standard SQL, ready to query.

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

A local database file, here finance.db in the current folder. No server, good for personal dashboards and offline analysis.

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

A snapshot file, rewritten on each run. Opens anywhere.

sheetlink sync --output csv --file ~/finances.csv

Structured JSON on stdout. Pipe it to jq, pandas or your own scripts.

sheetlink sync | jq '.items[].transactions | length'

What people run once their bank data is a command away.

With a Max API key, cron runs sheetlink sync at 7am and your database is current before you are. Nothing runs unless that line does.

0 7 * * * SHEETLINK_API_KEY=sl_… sheetlink sync --output postgres://localhost/finance

SheetLink becomes a read-only bank data source: JSON into pandas, dbt, or anything that reads stdin.

sheetlink sync | jq '.items[].transactions[]'

Sync to Postgres or SQLite, then point Metabase, Grafana or your own app at it.

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

Holdings and investment activity, with cost basis and gain or loss, in sheetlink_investment_holdings and sheetlink_investment_activity.

sheetlink investments --output postgres://localhost/finance
