Since data types are used in Alteryx’s data preparation and computations, an in-depth knowledge of them is necessary. Numerous data types, like Numeric, String, Boolean, Date-time, as well as Spatial Objects, are supported by Alteryx. With Select Tool, the majority of data types may be modified or transformed to satisfy particular needs. Let’s explore each group of data types by looking at the factors to take into account when defining as well as transforming data types in Alteryx.

Alteryx Data Types
With proper training, you can have a clear idea of several segments of Alteryx data types are:
Numerical Data
Alteryx supports multiple numerical data types, including double, float, decimals, and integers data.
Bit
The sole positive whole values that this data type allows are 0 to 255 or 28.
It16
In Alteryx training, you will learn Integer with a value of 2 bytes, devoid of a decimal place, and falling between -215 and +215-1, or -32768 and 32767.
Int32
A number that can take values between -2,147,483,648 and 2,147,483,647 and is equivalent to 4 bytes sans decimal places and ranges from -231 – +231-1
Int64
An integer having a length of 4 bytes and no decimals that can take values between -263 and +263-1, or from –9,223,372,036,854,775,808 to 9,223,372,036,854,775,807
Unchanged Decimal
The number with a decimal place with lengths that can be modified depending on accuracy as well as decimal spaces is this sort of numeric data. The entire breadth of the data, which includes the -/+ signs, the decimal, as well as the digits preceding and after the decimals, is known as the length or precision. For instance, the precision as well as decimal place of the value -45.345 are 7 and 3, respectively.
Float
This type of data is used to store numerical numbers with exact decimal places. It has a precision of seven digits as well as can store values between +/- 3.4 x 10^38 plus 3.4 x 10^38 using only 4 bytes.
Double
This is a data type that resembles float but has more accuracy. With an accuracy of 15 digits, it is capable of holding values between +/- 1.7 x 10^308 as well as 1.7 x 10^308 using only 8 bytes.
String Data
String data, containing alphabetic, numeric, space, and various other type of characters, is used for storing every text-related data. String, WString, V_String, as well as V_WString are all of the different forms of data that make up string data.
String
The string has a limited length and can only include Latin-1 letters. There can only be 8192 letters in it. Setting a limit of characters on the maximum value which ought to be placed in the field is advised. The figures are trimmed if the value exceeds the predetermined limit. For instance, ‘Altreyxisfun’ would show as ‘Altreyxisf’ if the string’s limit was set to 10.
WString
WString (Wide String), like the string data type, supports any type of character, including Unicode as well as other characters from other worldwide languages.
V_String
The data type known as Fixed Length String (V_String) modifies its length flexibly to fit the string data that is kept in a field. Simply Latin-1 characters are supported.
V_WString
Variable Length Wide String (V_WString) supports Unicode as well as other foreign language elements which dynamically modifies its length to fit the string data management placed in this field.
Spatial Objects
SpatialObj
The digital representations of physical things utilized for data administration and analysis are stored as spatial objects in this form of data. A single point, line, polyline, or hexagon may be included.
Date/Time Data
Date
The date value in Alteryx is stored as a 10-characteristics string variable in a format called “yyyy-dd-mm.” For Alteryx to function, any fields containing additional date formats must be converted to the new format. For instance, the July 31, 2020 DateTime parsing tool needs to be modified to 2020-07-11.
Time
By default, it consists of 8-character string data in the format “HH:MM:SS.” To improve precision, we may enter an extra number of up to eighteen digits. For instance, time value 07:53:34 might have more digits specified to describe the accuracy in milliseconds, i.e.07:53:34.452
DateTime
The time and date values are represented in just one field by the DateTime data type. It is a string of nineteen characters in the format “yyyy-mm-dd hh:mm:ss”. like this: “2020-07-11 07:53:34”
Boolean Data
Bool
There are just two potential values for the data type: zero, which indicates false, as well as any non-zero number, which indicates false. For example, if the field is of the bool data type as well as contains numbers such as 0, 1, 2, and 3, then 0 is regarded as “False” and the remaining non-zero values (1, 2, 3) as “True.” The true and false values for this area should be represented by the binary digits (1 and 0).
