The CSV import app is part of Airtable Apps, a Pro plan feature. Apps let you extend the functionality of your bases: you can use apps to bring new information into Airtable, visualize and summarize your records in colorful ways, and even directly integrate your Airtable bases with your favorite apps.
With the CSV import app, you can add new records to an existing table in your base from a CSV file. You can also update existing records in a table from a CSV file by picking a specific field to merge on. The CSV import app has a 25,000 row limit.

After installing a CSV import app, you can drag and drop a CSV file onto the app. After your file gets uploaded, you'll be brought to a screen where you can map exactly how the information from the CSV gets put into your table.

Before mapping the fields, make sure you have the correct table selected.
The app will automatically try to detect if the first row of your CSV is comprised of headers or not, and check the "First row of CSV file is headers" option accordingly. If this option is checked, the columns in the field mappings section of the app will be named after the CSV's column headers. If this option is not checked, the columns in the field mappings section of the app will be given generic names like Column, 1, 2, 3, and so on.
The left side of the Field mappings section (with the toggles) shows the fields in your table, and the right side (with the dropdowns) shows the columns of the CSV. If the columns of your CSV and names of the fields in your table have matching names, the app will automatically try and match them. Otherwise, you can map the columns of the CSV to whichever fields you'd like.
To map a value, select the field toggle, then choose a CSV column from the dropdown menu. Repeat this process for as many fields as you want.
Note that you don't have to import any fields you don't need to, and the order and names of the fields in your CSV don't necessarily have to match the order and names of the fields in your Airtable base. As you alter the field mappings, you can look at the right side of the app, which shows samples of the records that will be created according to the specified mappings.
Once you're ready, click the Create records button.
The app will remember your field mappings the next time you import another CSV, speeding up the process if you plan on importing CSVs again and again as part of your workflow.
Updating existing records with the CSV import app
In addition to creating new records with the CSV import app, you can also use the CSV import app to update existing records. To do this, you'll need to pick a field on which to merge records (ideally containing a unique value like an ID number or email address, for example). The app will then compare the records in your table with the rows in your CSV, find matches using the field you selected, and update the values in the table according to the contents of the CSV file.
To get started, drag and drop a CSV file onto the app.
Next, click the Merge with existing records toggle. You will then be prompted to pick a field: the app will use whichever field you pick to compare your existing records with the values in the CSV file.
Matching for the field you select will be case-sensitive; for example, the app will consider "sampleemail@example.com" and "SampleEmail@example.com" to be two different values. (However, leading and trailing whitespace will be ignored when finding matches.)
Once you pick a field, the app will display previews for the records to be updated. If the CSV being imported contains rows which have no matches in the table, the app will create new records. The bottom of the app window will show the number of records that will be updated, the number of records that won't change, and the number of new records that will be created (if any).
A few other notes on the updating process:
- If the CSV file contains multiple rows which contain the same value for the merge field, the app will only use the first of those rows, and subsequent rows will be ignored.
- If the table has multiple records, all of which contain the same value for the merge field, all of those records will be updated if there's a matching row in the CSV file.
- If the CSV contains any rows where the value in the merge field is blank, a new record will be created.
If everything looks good, click the Save button.
Create missing select options
You can now create new select options in single and multiple select fields when importing a CSV—just be sure to check the toggle that says “Create missing select options.”
