Tableau for Data Analyst – Tableau Functions

Personal Career & Learning Guide for Data Analyst, Data Engineer and Data Scientist

Tableau is a powerful data visualization tool that can help data analysts create meaningful insights from large amounts of data. One of the key features of Tableau is its extensive set of functions, which allow users to perform complex calculations on their data and turn it into useful information.

Tableau functions can be used to perform a variety of operations on data, including mathematical operations like addition and subtraction, string operations like concatenation and extraction, and date operations like date difference and date parsing. These functions are easy to use and can be applied to entire columns or specific cells in a Tableau data source.

To use a Tableau function, a user first needs to select a data field and then choose the appropriate function from the Functions dropdown menu. Once a function has been applied, the user can modify its parameters to customize the calculation and obtain the desired result.

Some of the most commonly used Tableau functions include:

  • SUM: Calculates the sum of all values in a field.
  • AVG: Calculates the average of all values in a field.
  • MIN: Returns the minimum value in a field.
  • MAX: Returns the maximum value in a field.
  • COUNT: Counts the number of items in a field.
  • IFNULL: Returns a specified value if a given expression is NULL.
  • NOW: Returns the current date and time.
  • DATEDIFF: Calculates the difference between two dates.
  • DATEPARSE: Parses a string and returns a date value.


There are many other functions available in Tableau, and users can also create their own custom functions if needed. By using Tableau functions, data analysts can perform complex calculations and manipulations on their data, and turn it into meaningful insights that can be used to inform business decisions.

In conclusion, Tableau functions are an essential tool for data analysts, and play a key role in transforming raw data into useful information. Whether you’re looking to perform mathematical operations, string operations, date operations, or other types of calculations, Tableau functions are the perfect tool to help you achieve your goals. So, if you’re a data analyst looking to take your skills to the next level, it’s worth taking the time to learn about Tableau functions and how they can help you make the most of your data.
