# What Is a CSV File?

## Understanding CSV files and why HUSL uses them to import client data.

A **CSV file (Comma-Separated Values)** is a simple text file that stores data in a table format—similar to a spreadsheet. Each piece of information is separated by a comma, making it easy for different software systems to read and transfer information.

HUSL requires a CSV export when importing client data from another software because CSV files are **universal, lightweight, and compatible** with almost all booking, POS, and CRM systems. This ensures client information is transferred accurately and efficiently.

#### **Why HUSL Requires a CSV File**

Using a CSV file allows HUSL to:

- **Standardise data** from different platforms
- **Prevent formatting issues** during import
- **Streamline the upload process** for faster setup
- **Reduce errors** when mapping fields like names, emails, services, and visit history

#### **How to Export a CSV File from Your Current Software**

While every software is slightly different, the general steps are similar:

1. **Log in** to your current software.
2. Navigate to **Clients**, **Contacts**, or **Data Management**.
3. Select **Export** or **Download**.
4. Choose **CSV** as the file format.
5. Save the file to your computer.
6. Upload it to **HUSL** during your client import step.

#### **💡 Tips for a Smooth Import into HUSL**

- **Check for duplicates** before exporting.
- Make sure email, phone, and name fields are **up to date**.  
  \*NOTE: Customers without mobile numbers cannot be imported.
- Remove any special characters that may cause formatting errors.

If possible, include **client notes** to ensure a complete transition.
