  1. Tableau - Data Types Tableau Swipe

  2. Tableau - Data Types As a data analysis tool, Tableau classifies every piece of data into one of the four categories namely :- String Number Boolean and datetime. Once data is loaded from the source, Tableau automatically assigns the data types. Contrarily, you can also change some of the data types if it satisfies the data conversion rule. The user has to specify the data type for calculated fields.

  3. STRING String functions allow you to manipulate string data (i.e. data made of text). For example, you might have a field that contains all of your customers' first and last names. You can pull the last names from all your customers into a new field using a string function. Example:- 'Hello' 'Quoted' 'quote'

  4. NUMBER Number functions allow you to perform computations on the data values in your fields. Number functions can only be used with fields that contain numerical values. For more information, see Data Types. For example, you might have a field that contains values for the variance in your budget, titled Budget Variance. Example:- 3/142.58

  5. BOOLEAN In Tableau, Boolean is either True or False. It can only be one of those values. In some software a tri-state data type – True, False, Null – can sometimes be mistakenly referred to as boolean, for example a SQL bit data type. In terms of performance, Boolean is as good as it gets. Example:- TRUE/FALSE

  6. DATE & DATETIME Tableau recognizes dates in almost all formats. But in case we need to force Tableau to recognize a string as date, then we put a # sign before the data. Example:- "02/01/2015"/"#3 March 1982"
