# String Builder

### StringBuilder <a href="#stringbuilder" id="stringbuilder"></a>

**StringBuilder** is used to concatenate strings when building up a string in a loop.

StringBuilder is used in conjunction with the **SetValue** function. Drag a SetValue function below the StringBuilder function to assign more strings using the SetValue target property.

#### Value <a href="#value" id="value"></a>

A write-only variable that can be used to add a string to the end of the current string.

To use, select 'Append' from the drop-down list of the *Target* property of the [SetValue](/reference/plugins/linx/content/setvalue.md) function, and enter the value that must be appended in the *Source* property.

#### AppendLine <a href="#appendline" id="appendline"></a>

A write-only variable that can be used to add a string to the end of the current string, and adds a line-terminator afterwards.

To use, select 'AppendLine' from the drop-down list of the *Target* property of the [SetValue](/reference/plugins/googlesheets/content/values/batchgetvaluesbydatafilter.md) function, and enter the value that must be appended in the *Source* property.
