# Bulk Import rows
It can be a tedious process to manually insert or update several rows. In such cases, you can bulk import the data directly from an external file.
Import bulk data
PowerTable allows you to insert and update multiple rows at once by importing CSV or Excel files. The rows are updated based on matching primary keys from the file.
1. To import new rows, click **Import** on the toolbar that opens the 'Import from file' pop-up.
2. Click on the space to upload an Excel or a CSV file.
3. Select the required file from the systems folder and click **Upload.**
4. You can view the uploaded data.
* Records with existing primary keys are updated.
* Records with new primary keys are inserted as new rows.
* Mismatches are flagged as errors that can be resolved by clicking on logs.
