How to Import Data via CSV in Attio: Step-by-Step Guide
Begin by navigating to the Collection that holds the type of data you want to import. Whether it’s Companies, People, Deals, or a customized Collection, make sure you’re in the right place to keep your information organized effectively.

For this example, we’ll focus on the Companies Collection. Selecting this Collection will ensure your data imports into the correct category, making future management easier.

Within the Companies Collection, look for the option labeled "Import / Export". This is your gateway to managing external data files and syncing information from outside sources.

After clicking Import / Export, select "Import CSV". This option allows you to bring in bulk data saved in CSV format—a common spreadsheet type easily exported from many tools.

Next, choose the CSV file from your device by clicking "Choose a CSV file". Make sure you select the file that contains the data you want to add to your Collection.

Once your file is selected and uploaded, move forward by clicking the "Next" button. This will take you to the stage where you can review your data before it’s imported.

Here, you have the opportunity to carefully review and adjust the attributes mapped from your CSV. This ensures each field matches your Collection’s setup. When you’re satisfied, click Continue to proceed.

To kick off the import process, select "Start import". This initiates the transfer of your CSV data into the selected Collection.

For final confirmation, click on "Start import" once again. This double confirmation helps prevent accidental imports and confirms you’re ready to bring your data in.

After the import completes, your data is ready to use. You can now take any necessary actions like editing, sorting, or linking this new information within your Collection to enhance your workflow.
