Let’s briefly look into each of them:

Data Type for Strings Text Data type

  • To enclose characters, use single or double quotations.
  • There are two sorts of string values:

– Varchar and Char.

Data Type for Char

  • If you enter a value that is more than the predefined limit, an error message will appear.
  • alpha-numeric values are saved

Varchar Type of Data

  • Variable character is referred to as Varchar.
  • The string’s length is adjustable, so you can enter as many values as you like.
  • alpha-numeric values are saved

Data Type for Date and Date & Time

  • Tableau supports all date formats, including mm-dd-yyyy and dd-mm-yyyy.
  • An extension of the Date data type is the Date and time data type.
  • Seconds, minutes, hours, days, months, years, decades, and other time units are all possible.
  • Add the # symbol before the date value if you want to add it as a string. For instance: # 11 March 2022

Numeric Data Types

  • Numerical values may either be:
  • – An integer Integer Floating: 10, -5, 0
  • Decimal floating values: 2.536, 0.6667, and -3.14
  • Since it becomes challenging to add more decimal points at a certain point, integer values are preferred over floating-point numbers.
  • To round the float values, use Round().

Type of Boolean Data

  • True or False are the two logical values for boolean data types.
  • Additionally, 1 and 0 use to denote True and False, respectively.
  • Is profit larger than zero, for instance?
  • “Yes” or “No” just
  • It is convertes to a boolean computation in the tableau:
  • SUMIFS([Profit]) > 0

Type of Geographical Data

  • In Maps Associates, data values use for each value in a field having a latitude and longitude value.
  • includes elements such the postal code, region, city, state, and nation, among others.

Mixed or Clustered Data Types

  • The data type can determine by Tableau, but occasionally the data field doesn’t match the data type.
  • Analyzing the data is a challenge when using mixed values.
  • Making a different column that doesn’t include the mixed values will cure this issue.


In this blog, we discussed a wide variety of data in Tableau, such as string, integer, date, date & time, Boolean, geographic, and mixed data types.

I hope this blog will be helpful to you as you come up with your data analyst career.
