Refreshing your data in Looker Studio is essential to ensure that visualizations are up to date and accurate—crucial for making informed business decisions. In this detailed guide, I'll walk you through various methods to effectively refresh your data in Looker Studio, drawing from my extensive experience with the platform.
To refresh a data source in Looker Studio, follow these steps:
For Google Sheets or Cloud Data Sources
- Open Your Report: Navigate to your Looker Studio report where the data source is connected.
- Edit Mode: Ensure you are in "Edit" mode by clicking the pencil icon in the upper-right corner of the screen.
- Select the Data Source: In the report, click on a chart or table that uses the data source you want to refresh. This will reveal the data source panel on the right.
- Click "Refresh": In the data source panel, click the refresh button (a circular arrow icon). This will fetch the latest data from the source, such as Google Sheets or BigQuery.
For Google Analytics, Google Ads, or Other Auto-Updating Data Sources
- These sources usually auto-refresh with a slight delay. However, to manually refresh them:
- Follow steps 1-4 mentioned above.
- Additionally, you can go to Resource > Manage added data sources to manage or update the connection.
For Cached Data (like BigQuery)
- Go to Resource: From the top menu, click Resource > Manage added data sources.
- Manage the Data Source: Locate the data source you want to refresh, click the three-dot menu on the right, and select Refresh Fields or Reconnect.
- Reconnecting ensures the schema changes in your data source (like adding or removing columns) are updated in Looker Studio.
For Scheduled Refresh (BigQuery, etc.)
- You can schedule automatic data refreshes by going to the Data Source Settings in Looker Studio and adjusting the refresh schedule to meet your needs.
