# How to Upload Product Data Manually (B2C)
### Before you begin
* File format: Prepare a spreadsheet (Excel) with all required product data, if you have a CSV file you can open it here: and export it as an Excel instead.
### 1. Open Settings
In Claimlane's inbox, click Settings in the bottom-left corner.
### 2. Select Your Data Source
* In the left menu, click Self-Service Portals.
* Choose your Self-Service Portal from the list.
* Click the Datasource tab
### 3. Choose the Data Source
From the datasource list, select the one you'd like to upload products to. (Click on Add new data source if you don't have one yet.)
### 4. Navigate to Products
* In the datasource view, go to **Products**
* Click Upload Products
### 5. Map Your Labels
* Click and drag each label from the panel into its matching column
* Important: All required labels (marked with \*) must be mapped before you can proceed.
{% hint style="info" %}
Note: Are you missing any label to match with your columns? You can go back to [Products (Step 4)](#h_9fe17b79c3) and click 
there you can create any needed label to match with your data and make sure to make it B2C.
{% endhint %}
### 6. Choose Your upload Mode
Once your labels are correctly mapped, you have two options in the top-right corner:
* Upload and add existing products: Use this when you are uploading only new products and you want to add them to your already existing product list.
* Delete existing products and upload: Use this when you want to replace your entire product list with the current list you are uploading (Note: If you have no previous product list, don't worry you can use this option)
Click on your chosen option.
### 🎉 You’re Done!
After selecting your upload mode, Claimlane will process your file.
