Copy Column Values

The Copy Column Values task copies values from a given column to a new Column.

When to use

• To create a backup of a column’s values.

• To copy values from one column into another.

• To copy values from a column based on a criterion.

Quick Start

Let us start with the following sample data:

Table 22 Birthdays → View 1

Student	Science	English	French
Alice	140	138
Bob	135	145
Frank	122		102
Judy	185		135

In this sample data, it is evident that the student takes only one of the two language subjects. Our goal is to consolidate the values of English and French columns into a new column named Language

Table 23 Birthdays → View 1

Student	Science	English	French	Language
Alice	140	138		138
Bob	135	145		145
Frank	122		102	102
Judy	185		135	135

Following are the steps to achieve our goal:

1. Open Data Preparation menu and click on Column Function

2. Select Copy Column Values

3. Choose the column English and add a condition that says English has Non Empty Values

4. Enter Language in the new column and hit APPLY. This will create a new column called Language and fill in the values from column English into column language wheresoever it has a value

5. Open Data Preparation menu and click on Column Function

6. Select Copy Column Values

7. Choose the language French and add a condition that says French has Non Empty Values

8. Select the column Language in result section and hit APPLY

Note: English and French can be removed by deleting columns

The resulting data should now look like below:

Table 24 Birthdays → View 1

Student	Science	Language
Alice	140	138
Bob	135	145
Frank	122	102
Judy	185	135
