To sync Google Sheets using Bracket, each sheet must have a primary field column that contains unique values. This can be as simple as an integer, or more complex like a UUIDv4.

Empty values count as primary key values, which can lead to data mixing in two-way syncs! Be careful to ensure that the primary key field is never empty for any syncs that read from Google Sheets

How to set up your primary key

For one-way syncs that read from Google Sheets, the primary key for any populated rows must have a static unique value. This value must never be changed, or data duplication can occur.

For all other sync configurations, the primary key must sync with a field in the opposing data source that is itself unique.

For example, if you are syncing Postgres with G Sheets in a two-way sync, the G Sheet primary key should sync with the Postgres primary key field in the field mapping

In summary:

ConfigurationPrimary key requirements
One-way sync from G SheetsPrimary key must be a unique, unchanging value, and identified as the primary key during setup
All other configurationsPrimary key must be in the Bracket field mapping, must sync with a field of unique values in the op posing data source, and must be identified as the primary key during setup
