The **Import** feature allows you to upload data files saved on your computer into Glide apps. The supported file formats include: * [Microsoft Excel](/docs/essentials/data-sources/microsoft-excel) spreadsheet (.xlsx) * Comma-separated values file (.csv) * OpenDocument Spreadsheet (.ods) > **Note** > > Data files can be imported into both Glide Tables and Glide Big Tables. You can upload these files three ways—while setting up a new app, by adding a new data source in the [Data Editor](/docs/getting-started/introduction-to-the-data-editor), and importing data into an existing Glide Table. ## Creating a New App #### Import file - Arcade 1 From the dashboard, select **New app.** Click on **Import File** and select **Continue**. Select **Choose a file** and select a file to upload. Select **Continue**. ## Adding a New Data Source #### Import File - Arcade 2 From the Data Editor, click on the **plus (+) sign** next to **Tables** and select **Excel or CSV** under **Import File.** In the pop-up, click **the arrow** and select a file to upload or **drag and drop** a file to the same location. ## Importing to an Existing Glide Table #### Import File - Arcade 3 From the Data Editor, select the exist table you want to import data into. There are two ways to import data into the table: * Right click on the table and select **Import.** * At the bottom left of the table view, select the **Import** button. In the pop-up, click the arrow and select a file to upload or drag and drop a file to the same location. > **Note** > > The sheets in your file are added as individual tables in the **Data Editor**. Since the original file is saved on your computer, any changes you make there will not affect the table in Glide and vice versa. > > When the imported file includes columns that aren't found in the current table, new columns are added to the end of the table. > Add data from files saved locally on your computer.
