How to Add Column in Alteryx

In Alteryx, creating a new column involves adding a field to your existing dataset and populating it with values based on certain conditions or calculations. Here’s a step-by-step guide on how to create a new column in Alteryx:

1. Input Data: Start by bringing in the dataset to which you want to add a new column. This can be an Excel file, CSV file, or any other data source. You can use the “Input Data” tool in Alteryx to connect to your data source.

2. Use the “Formula” Tool: To create a new column, you’ll need to use the “Formula” tool in Alteryx. The “Formula” tool allows you to perform calculations and define new fields based on expressions or functions.

3. Configure the “Formula” Tool: Connect the “Formula” tool to your input data source. In the tool’s configuration window, you’ll see a list of existing fields in your dataset. 

4. Add a New Field: Click on the “Add” button in the “Fields” section of the “Formula” tool. This will open a new field configuration window where you can define the properties and expression for the new column.

5. Name the New Field: Provide a name for the new column in the “Field Name” field. This name will be used to identify the column in the output dataset.

6. Define the Expression: In the “Expression” field, write the expression or calculation that determines the values for the new column. You can use mathematical operators, functions, and existing field names to construct the expression. For example, you can use an expression like “FieldA + FieldB” to add the values of FieldA and FieldB together.

7. Data Type and Format: Specify the data type and format for the new column based on the type of data it will contain. Alteryx provides various data types such as string, integer, decimal, date, etc.

8. Apply the Formula: Once you have defined the expression and set the data type, click the “Apply” button to save the configuration.

9. Run the Workflow: Run the Alteryx workflow to execute the formula tool and create the new column. The output dataset will now contain the newly created column with the specified values.

10. Output the Dataset: Finally, you can use the “Output Data” tool in Alteryx to save the modified dataset with the new column to a file or database.

By following these steps, you can easily create a new column in Alteryx and populate it with values based on your desired calculations or conditions.

How to Add Row in Alteryx?

In Alteryx, you cannot directly create a new row within the same data stream. However, you can achieve a similar effect by duplicating an existing row and modifying the duplicated row as needed.

Here’s how you can create a new row in Alteryx using the “Multi-Row Formula” tool:

  • Drag and drop a “Multi-Row Formula” tool onto your Alteryx workflow canvas.
  • Connect the incoming data to the Multi-Row Formula tool.
  • Double-click on the Multi-Row Formula tool to open its configuration window.
  • In the configuration window, you’ll see a text box where you can enter your formula.
  • To create a new row, you can use the following syntax: [Field1], [Field2], …, [FieldN]

Replace [Field1], [Field2], …, [FieldN] with the values you want to assign to each field in the new row.

For example, if you have fields like “Name”, “Age”, and “Gender”, and you want to create a new row with the values “John”, 25, and “Male”, the formula would be: ‘John’, 25, ‘Male’

  • After entering the formula, click the “OK” button to close the Multi-Row Formula tool’s configuration window.
  • Run your workflow to apply the creation of the new row.

The output of the Multi-Row Formula tool will include the existing rows from the input data, as well as the newly created row with the specified values.

Remember that the Multi-Row Formula tool operates on a row-by-row basis, so if you want to create multiple new rows, you need to duplicate the Multi-Row Formula tool and configure each one with different values.

How do I create an empty column in Alteryx?

To create an empty column in Alteryx, you can use the “Formula” tool and provide a blank or null value for each row in that column. Here’s a step-by-step guide:

  • Drag and drop a “Formula” tool onto your Alteryx workflow canvas.
  • Connect the incoming data to the Formula tool.
  • Double-click on the Formula tool to open its configuration window.
  • In the “Fields” section, click on the “+” button to add a new field.
  • Enter a desired name for the new column in the “Name” field.
  • In the “Expression” field, input a blank value or null value. Here are a couple of options:
  • For a blank value: “”
  • For a null value: NULL()
  • Choose the appropriate option based on your requirements.
  • Click the “OK” button to close the Formula tool’s configuration window.
  • Run your workflow to apply the creation of the empty column.

The output of the Formula tool will include the existing data rows, with the newly created empty column appended to the right. Each row in the empty column will contain either a blank value or a null value, depending on the expression you used.
