# Whalesync ID column

To enable syncing, Whalesync adds a “Whalesync ID” column to each sheet in your Google Sheets.

#### Why does Whalesync need to add a Whalesync ID column?

Unlike most apps and databases, Google Sheets doesn’t assign a unique ID to each row. To enable syncing, Whalesync adds its own ID column to uniquely identify each row.

#### Can I edit this column?

In general, you want to avoid editing this column since it is how Whalesync identifies each row. For example, this is why we suggest [avoiding sort range](/connectors/google-sheets/avoid-sort-range.md).
