How to Connect Your Bank Accounts to a Spreadsheet
The practical guide to setting up automatic transaction syncing in Google Sheets and Excel — so your financial data arrives every morning without any manual work.
Getting your bank transactions into a spreadsheet manually works — until it doesn’t. The moment you’re managing more than one account, or you want numbers that reflect this week (not last week), the CSV download routine starts to fall apart. Logging into multiple bank websites, exporting files in different formats, cleaning up column headers, merging everything by hand — it’s 20–30 minutes of work every time you want current data.
A direct bank connection solves the maintenance problem. When your accounts are linked to your spreadsheet, transactions arrive automatically. Balances update. Categories are suggested. You open your sheet and the data is already there.
This hub covers the how: how bank-to-spreadsheet connections work, how to set one up in Google Sheets or Excel, how to sync transactions automatically, and how to automate categorization once the data is flowing. Several guides here feature Tiller, which handles the bank connection and daily data delivery so the pipeline runs without you.

How a Bank-to-Spreadsheet Connection Actually Works
When you connect a bank account to a spreadsheet tool like Tiller, you’re not sharing your login credentials with a third party. The connection happens through a financial data aggregator — a company (like Plaid or MX) that specializes in securely linking financial institutions to other services. These are the same aggregators that power many banking apps and financial tools you already use.
The connection is read-only. The service can see your transactions and balances, but it cannot move money, initiate transfers, or make any changes to your accounts. You authorize access through your bank’s own interface, and you can revoke it at any time.
Once the connection is active, it runs in the background. Every morning, the aggregator checks for new transactions and passes them to your spreadsheet automatically — no action required on your part. Most major banks, credit unions, credit cards, and investment platforms are supported through these aggregator networks, though coverage can vary by institution.
