Explain the String Function ' LTRIM ' in Tableau with Example?

 In Tableau, the LTRIM function is used to remove leading spaces (spaces at the beginning) from a string. It returns a new string with the leading spaces removed.

The syntax for the LTRIM function in Tableau is as follows:


Here's an example to illustrate how the LTRIM function works:

Let's consider a dataset with a column named "Name" that contains various names, some of which have leading spaces.


John Doe

Jane Smith

Alex Johnson

Mark Anderson

Kate Brown

In Tableau, we can create a calculated field using the LTRIM function to remove the leading spaces from the "Name" column. Let's call this calculated field "Trimmed Name."


The above expression applies the LTRIM function to each value in the "Name" column, removing any leading spaces.

Applying this calculated field to our dataset, the result would be:

Name                                                 Trimmed Name

John Doe                                                             John Doe

Jane Smith                                                      Jane Smith

Alex Johnson                                                     Alex Johnson

Mark Anderson                                             Mark Anderson

Kate Brown                                                        Kate Brown

As you can see, the "Trimmed Name" column contains the names with the leading spaces removed, resulting in a cleaner representation of the data.

The LTRIM function can be useful when dealing with data that may have inconsistencies or unwanted spaces at the beginning of string values. By applying the LTRIM function, you can ensure consistency and improve data quality in your analysis or visualizations.
