If Formula Looker Studio: Essential Functions for Data Analysis

In Looker Studio, the if formula is a game-changer for data analysis. It allows you to create dynamic content that changes based on the value of a cell.

You can use the if formula to display different values or messages based on certain conditions. For example, you can show a specific message when a value is greater than a certain threshold.

One of the most useful applications of the if formula is to create conditional formatting. By using the if formula, you can change the color or style of a cell based on the value it contains.

The if formula can also be used to create more complex logic statements, such as displaying one value if a condition is true and another value if it's false.

To maintain uniformity within the IFNULL function, the result type must be consistent. If the field with missing values is text, the replacement value must also be text.

The IFNULL function is used to display missing values as a specific value instead of null. For example, using the formula IFNULL(refund, 0) will display missing values in the refund column as 0.

Conditional functions in Looker Studio, such as IFNULL, are used to perform different actions based on different conditions. The IFNULL function specifically returns a result if the input expression is null.

Displaying missing values as 0 is a crucial step in maintaining uniformity in your data. This is particularly important when working with data that contains empty cells, as seen in the example of refunds data.

The IFNULL function is a powerful tool for achieving this. By using the formula IFNULL(refund, 0), you can replace missing values with a value of 0, as demonstrated in the example.

This simple yet effective solution ensures that your data is consistent and easy to work with. For instance, in the case of refunds data, displaying missing values as 0 makes it easier to represent daily refunds in a Looker Studio table.

The new field 'refund_ifnull' created through this process can then be used in your report to display the missing values as 0, as seen in the example. This approach helps to maintain the integrity and usability of your data.

Ensuring uniformity in your data is crucial when dealing with missing values. This means that all IFNULL functions should return the same type of result.

In other words, if you're replacing missing values with text, you must use text for all replacement values. This ensures that your data remains consistent and accurate.

For example, if the field with missing values is a date, the replacement value should also be a date. This helps maintain the integrity of your data and prevents errors down the line.

Using uniformity in your IFNULL functions also makes it easier to analyze and work with your data. It's a simple yet important step in data management that can save you time and headaches in the long run.

Conditional functions in Looker Studio are like the "if-then" statements of the data world. They help you perform different actions based on different conditions.

You can use the IF function to return one result if a condition is true and another result if it's false. The syntax is IF(condition, true_result, false_result), and it's as simple as that.

The IFNULL function is another useful one. It returns a specific result if the input expression is null, which can be super helpful when dealing with missing data.

The NULLIF function is similar, but it returns null if the two input expressions are equal. This can be useful when you want to check if two fields are the same.

The COALESCE function is a bit more complex, but it's still easy to understand. It returns the first non-missing value found in a list of fields, which can be helpful when you have multiple fields to choose from.

Here are the conditional functions available in Looker Studio:

You can create calculated fields in Looker Studio to automate complex calculations, like weighted averages. To illustrate, let's calculate the total CTR for a Facebook Ads campaign over 7 days.

The basic formula for CTR is clicks / impressions, but for a weighted average, you use sum (clicks) / sum (impressions). To do this, type SUM(clicks)/SUM(impressions) in the Formula field and use automatic prompts to speed up the process.

You can then name the field and click save. This will create a new field, which you can drag into the metric section and modify to display as a percentage.

To get an accurate total CTR, check the Summary row box in the right side panel. The same type of summation formula can be used to get weighted averages for other total calculated metrics, like total ROAS.

The formula for total ROAS is sum (revenue generated by ads) / sum (cost of ads). You can also use sum (total advertising cost) / sum (total number of clicks) to calculate total CPC.

Using the IF formula is a powerful way to combine metrics in Looker Studio. You can use it to create a new dimension or metric based on a condition.

To use the IF formula, you need to specify a condition, a result if the condition is true, and a result if the condition is false. Looker Studio will let you know if the formula is valid or not.

If your formula is valid, you can change the type of dimension or metric. For example, if you've created a dimension as an image, you can change its type to a number.
