Create and manage data sets

A data set in the context of file upload is a collection of files with the same structure. Once a file upload data set exists in Looker Studio, you can connect to it and create data sources that use that data, just as you would with other types of data.

Create a data set

To create a data set, create a new File Upload data source and add a file to it:

1. Sign in to Looker Studio.
2. On the Looker Studio home page, in the top left, click Create, and then select Data Source.
3. Choose File Upload in the Connectors panel.
4. Drag one or more files from your computer to the upload target, or click UPLOAD FILES and select the files you want.

Your files will be added to the data set.

Edit a data set

There are 2 ways to edit a data set: by editing the connection of a data source based on the data set, or by going through the connectors panel.

Edit the data source connection

1. Sign in to Looker Studio.After signing in, you'll see the Home page.
2. Click the DATA SOURCES tab.
3. Click a data source that uses the data set you want to edit.
4. Click EDIT CONNECTION in the upper left.

Use the connectors panel

1. Sign in to Looker Studio. After signing in, you'll see the Home page.
2. Click the DATA SOURCES tab.
3. Click .
4. Choose File Upload in the Connectors panel.
5. Click the data set you want to edit.

Add data to a data set

You can add more files to a data set at any time. Edit the data set and click ADD FILES. Then, select one or more files to upload. There is no need to click RECONNECT. Any data sources that use the data set will automatically be able to access the new data.

Delete an upload file

Deleting an upload file removes its data from the data set. You can't undo this (though you can upload the same file again, if needed).

1. Edit the data set.
2. Mouse over the file you want to delete.
3. Click the trash icon appears on the right.

Rename a data set

When you first create a data set, it gets named using the name of the first file uploaded. To rename a data set:

1. Edit the data set you want to rename.
2. Click the current name in the files panel and enter a new name.

Delete a data set

Deleting a data set permanently removes all the uploaded files.

1. Edit the data set you want to delete.
2. Click DELETE DATA SET at the bottom of the file list.

Fix upload errors

If your upload file has errors, Looker Studio will display an error in the Status column of the file list. Click ERROR to display the actual problem found. Almost all these errors will be due to unexpected formatting in the uploaded file.

Use an existing data set in a new data source

You can reuse data sets in any number of data sources.

2. Select File Upload in the Connectors panel.
