Information noteThe "Set verbatim=1" statement is included in the example to ensure that the spaces are not automatically trimmed before the demonstration of the LTrim function. See Verbatim for more information.

Load the data and open a sheet. Create a new table and add this field as a dimension:
InputText
Create the following calculated dimension:
=LTrim(InputText) to remove leading spaces from InputText.
Results table
InputText
LTrim(InputText)
' abc '
'abc '
' def '
'def '
The output of the LTrim function removed all leading spaces to the left of the original text but retained all trailing spaces.
Example - LTrim scenario
Overview
A customer relationship management (CRM) system contains records with inconsistent data entry that include extra leading spaces. For reporting purposes, the data requires cleaning to remove these spaces and to ensure proper sorting and grouping of customer names.
Open the Data load editor and add the load script below to a new tab.
The load script contains:
A dataset which is loaded into a data table called Example.
One field in the data table called CustomerName.
Load script
Set verbatim=1;
Example:
Load * inline [
CustomerName
' John Doe'
'Jane Smith'
' Michael Johnson'
'Emily Davis'
];

Load the data and open a sheet. Create a new table and add this field as a dimension:
CustomerName
Create the following calculated dimension:
=LTrim(CustomerName) to remove any leading spaces from CustomerName.
Results table
CustomerName
LTrim(CustomerName)
' Michael Johnson'
'Michael Johnson'
' John Doe'
'John Doe'
'Emily Davis'
'Emily Davis'
'Jane Smith'
'Jane Smith'
The output shows that the LTrim function removed all leading spaces from the original string values in CustomerName.
Example - LTrim advanced scenario
Overview
This example removes all leading spaces from the original text string. The chart expression includes measures that use the Len function to count the characters in the string before and after using the LTrim function.
Open the Data load editor and add the load script below to a new tab.
The load script contains:
A dataset which is loaded into a data table called Example.

Load the data and open a sheet. Create a new table and add this field as a dimension:
String
Create the following calculated dimension:
=LTrim(String), to remove any extra leading spaces.
Create the following measures:
=Len(String), to count the length of the original string.
=Len(LTrim(String)), to count the length of the string after the leading spaces have been removed.

When you compare the output of the LTrim function to the original string values in the script, you can see how all leading spaces have been removed.
The following code shows how to use the function in a load script.
Set verbatim=1;
Example:
Load *,
len(LtrimString) as LtrimStringLength;
Load *,
ltrim(String) as LtrimString;
Load *,
len(String) as StringLength;
Load * Inline [
String
' abc '
' def '];
