### **Example 1**

**Checks if a column header exists or not in the Grid**\
\
The **Verify Column Header** action takes the value from the Input Value column (e.g., **Date;Not**) and checks whether the specified column header **(Date)** exists in the Grid. If "**Not**" is provided, it checks for the absence of the column. The result is stored in the **{Header}** variable, while the execution status is stored in the **{Status}** variable, with the following possible values:

* **True** – if the header is found&#x20;
* **False** – if the header is not found&#x20;
