If you want to import an existing customer database into Last.App, follow the step-by-step guide below.
Each external platform generates a file with the customer data it stores. It's important to convert this file into the format required by Last.App for the import to be successful.
You can find the official Last.App customer import format at the following link.
Below is an explanation of each column and the type of information it must contain:
+34
.If you’re missing some information for a customer, it’s fine to leave the field blank.
Here’s an example of two customers: one with complete data and one with some missing fields.
In the first case, the profile will be created with all the information filled in.
In the second case, the customer profile will be created without an email or postal code.
Once you have filled out the file with the correct customer data, you need to save it as a CSV file (Comma-Separated Values).
If you're working in Google Sheets, go to File > Download > Comma-separated values (.csv).
Once you have your CSV file ready, go to LastAdmin > Customers. There you’ll see the Import icon in the customer section.
Clicking on this icon will open your file explorer. Select your CSV file and click "Open". This will begin the import process, and you’ll see a confirmation message in the top-right corner of the screen indicating whether the file was uploaded successfully.
After the import is complete, the customers will appear in the admin panel once the data syncs with the server. This sync process can take up to 45 minutes, so you may not see the imported customers immediately.
All customers imported this way will show “CSV Import” as their source.
