# StringBuilder connector methods

The StringBuilder connector methods enable you to create, append, update, replace, or remove strings in your automation workflow in RPA Desktop Design Studio.

## Append

Adds string to an existing string. You can create multiple strings by using multiple copies of the method. To view the output, use the ToString method.

**Note:** The method doesn't insert a line between the strings.

</td><td>

</table>## AppendLine

Adds a string followed by a newline character \(\\n\) automatically. When you add multiple strings using multiple copies of the method, it inserts a line between the strings. It functions exactly like the **Enter** key on a Microsoft Word document. To view the output, use the ToString method.
