# Prepare your Google Sheet for SheetBridge
*Skill Level: Expert*
### **Introduction**
SheetBridge reads your first row as column headers and turns each column into a property in Adalo. A clean header row and consistent data makes setup faster and prevents sync errors.
***
### **Before You Begin**
* Make a copy of your spreadsheet before making structural changes (recommended).
* Ensure each tab you plan to connect uses a single header row (the first row) and a consistent structure.
* Column Headers should have ***unique names***. Duplicate Column names will result in missing data.
* Sheet Tabs should have ***unique names***. Duplicate Tab names will result in missing data.
* Remove Blank Rows at the bottom of the Google Sheet.
***
### **Set up your Header Row**
1. Open your Google Spreadsheet and choose the tab you want to use as a collection.
2. Make sure row 1 contains your column names (for example: name, email, status).
3. Use one header per column. Avoid merged header cells.
4. Avoid duplicate header names. Each header should be unique.
5. **Consistent data types:** Each column should maintain a single data type (text, number, date, or boolean)
6. **Normalize related data:** Separate customer information from order details into distinct sheets for better relationships
***
### **Understand the SheetBridge ID column**
SheetBridge automatically creates a ***sheetbridge\_id*** column to uniquely identify each row. This ID is used for updates and deletes.
{% hint style="danger" %}
**Important: The sheetbridge\_id column is system-managed. Do not rename, edit, or delete it, or the connection can break.**
{% endhint %}
***
### **Best practices**
* Use clear, simple header names (letters, numbers, and spaces).
* Keep data types consistent within a column (for example, do not mix dates and text).
* Avoid fully blank rows in the middle of your data.
* If you need to rename a column, verify any places in Adalo that reference it (Lists, Forms, Actions) are still connected properly.
