To generate formula built with ChatGPT API
1. Click on the Transform menu and select the Formula column option.
2. Click on the Formula builder powered by OpenAI ChatGPT tile to open up the the Formula prompt.
3. Describe the logic of your formula in natural language in the Formula prompt. As you enter the prompt, you can also mention the column names that you want the logic to apply to, and click Generate.
The required formula will be automatically generated in the Generated formula section.
You can get the output column names contextually auto-generated by ChatGPT based on your input prompt.
The Add formula transform is now equipped with a re-try mechanism which gets you the best result out of ChatGPT's response by re-trying the query automatically in a different way if the output data did not match your expectation.
Note: Entering column names within double quotes in the Formula prompt will generally yield better results. Example: "First_Name"
4. You can rephrase the prompt, or add more details till you get the required output. You can also click Customize, if you want to edit the generated formula.
5. Click Preview to see a preview of the changes made to the formula.
6. Click the Apply button to apply the transform.
Here are a few examples using natural language formula prompt.




To apply filters
If you want to apply some filters along with this transform, you can use the filters functionality.
1. Click the Filters tab.
2. Click the

icon and add the required columns in the
Filters section. You can also reorder the filters using the drag and drop method.
3. For every column added, you can select one of the following options from the drop-down:
- Actual: This option lets you filter rows based on the actual values in the column. Click here to know more.
- Data quality: This option lets you filter rows based on the quality of data in the column. Click here to know more.
- Patterns: This option helps you filter rows based on the data patterns in the selected column. Click here to know more.
- Seasonal: This option helps you filter rows based on the seasonal parameters such as quarter, month, week, etc. Click here to know more.
- Outliers: This option allows you to filter rows based on the outliers present in the data of the selected column. Click here to know more.
Note: The filter options are displayed based on the datatype of the column added for the filter.
4. When you add more than one filter to the Filters section, the logical operators, AND or OR appear next to the filters. You can click to toggle the logical operator between AND and OR.
- Using the logical operators, you can combine the conditions and apply logic to determine the rule of precedence. The final expression is displayed in the Criteria expression box. You can click Edit to alter the default expression using logical operators and parenthesis to specify the precedence or the sequential order as to which condition should be evaluated first. Click Save after making the required changes.
- For example, In the expression, ((1 OR 2) AND (3 OR 4)) , at first the condition ( 1 OR 2 ) will be executed and the condition ( 3 OR 4 ) will be executed next. Thirdly, since, the AND operator is used, the filter will be applied when both the conditions are true.
5. You can further drill down to choose specific values based on the filter option selected for each filter, in the next section.
For example, in the above screenshot, the Data quality option is selected for the All columns filter in the Filters section. Based on the selection, further options to filter specific values are displayed in the All columns (Data quality) section.
6. You can choose to include or exclude the selected items in the last section.
7. If you want to remove all the filters for some reason, you can use the Clear button.
8. A live preview of the filter transform is shown as you make changes.
9. Click the Apply button to apply the transform along with the filters.
