Exporting Data to CSV Format from Looker
- Looker provides multiple methods for exporting data to CSV. Users can export data from Looks, Explores, dashboards, legacy dashboards, and merged results queries. The primary methods include downloading data directly in CSV format and using the Looker Action for Google Sheets for CSV exports.
- To export data as a CSV from a Look or Explore, select the gear menu in the upper-right corner and choose "Download." In the Download window, select CSV from the Format field. Looker will download the data in CSV format. Users must have download_without_limit or download_with_limit permission from a Looker admin to download content.
- Users can export a dashboard as a collection of CSV files, which are delivered in a zipped format. Only query tiles are included; text tiles are excluded. Due to Looker's UTF-8 encoding, the CSV files might appear garbled. Looker suggests using a UTF-8-supporting file extractor like 7-Zip for extracting these files.
- Coefficient is the fastest method for exporting Looker data to CSV. It allows for a one-click export and supports automatic data updates. Using this method does not require any permissions from Looker.
- The Looker Action for Google Sheets sends CSVs directly from Looker to Google Sheets. This method requires admin setup but offers basic automation for data export. It is suitable for users who need to integrate data into Google Sheets regularly.
- When exporting data to CSV, note that Looker uses UTF-8 encoding, which may cause downloaded CSVs to appear garbled. A file extractor like 7-Zip, which supports UTF-8, is recommended for extracting zipped CSV files. Additionally, enabling custom row limits or choosing all results is disabled when downloading a dashboard as CSV files.

Important Considerations
How to Export Your Data to CSV Format from Looker
Permissions Required for CSV Export
A Looker admin must grant you either the download_without_limit or download_with_limit permission to download content as CSV. Without these permissions, exporting data will not be possible.
Exporting Data from Look or Explore
You can export data from a Look or Explore in multiple formats, including CSV. To do this, select the gear menu in the upper right corner of the Look or Explore page and then select Download. In the Download window, choose CSV from the Format drop-down menu. You may include the current result table, all results, or set a custom number of rows for your CSV export.
Exporting Dashboard Data
Looker allows you to download data from dashboards, legacy dashboards, and merged results queries as CSV files. Select CSV from the Format drop-down menu to download a dashboard as a collection of CSV files. The CSV files will be zipped and encoded in UTF-8. Use 7-Zip to extract the files to avoid garbled characters.
Downloading Merged Results Queries
To export merged results queries, download the entire dashboard as CSV. Looker includes data from merged results tiles in the zipped CSV files. You can also download specific dashboard tiles in CSV format.
Limitations on CSV Downloads
Looker does not allow unlimited CSV downloads for queries involving row totals, table calculations, percent of total, percent of previous, or running totals measures. Additionally, CSV downloads are restricted for queries from databases that cannot stream results or those with pivoted columns if the database cannot stream the pivots.
Custom Row Limits
When downloading data in CSV format, you can set custom row limits. By default, the number of rows is limited to 5,000, but this can be increased to 100,000 with the appropriate permissions.
Automatic File Naming
Looker automatically appends the corresponding file extension for the CSV filename. Ensure proper file management and naming conventions for ease of access and identification.
Export to Cloud Storage
Looker instance data can be exported to a Cloud Storage bucket. Use the Google Cloud console or the gcloud command line tool to execute exports. It is necessary to create a Looker service account with the required permissions and roles, including Storage Object Creator and Cloud KMS CryptoKey Encrypter, to perform these exports.
