Understanding Constraints     Bubble.io is a powerful no-code platform that allows users to build web applications without writing code. To automate data cleanup using workflows in Bubble.io, you need to understand Bubble’s database and workflow functionalities. The workflow consists of a series of steps that are triggered by specific actions or events, enabling tasks like data cleanup to happen automatically.     Setting Up Your Database     Before creating workflows, ensure your database is well-structured. Each type of data in Bubble.io is known as a "Data Type," and its attributes are called "Fields." Plan out which fields and data types need regular cleanup (e.g., removing duplicates, correcting formats).     Creating Custom Events     Custom events in Bubble.io allow you to group series of actions that can be triggered by other workflows. This is useful for modularizing your data cleanup tasks.  

• Go to the "Workflow" tab.
• Click on "Click here to add an event" to create a new workflow.
• Select "Custom Event."
• Name your custom event, e.g., "Data Cleanup."

    Triggering Workflow Events     You can decide how and when to trigger the data cleanup workflow. Common triggers are user actions, scheduled events, or specific database changes.  

• In the Workflow tab, click on "Click here to add an event."
• Select an appropriate trigger such as "Do when condition is true," "An element is clicked," or "Page is loaded."
• Set the conditions under which your workflow will be triggered.

    Adding Workflow Actions     Once the custom event and triggers are set up, you can add the actions that will perform the data cleanup. These actions could include data manipulation, data deletion, or formatting data.  

• Click on "Click here to add an action" within the workflow.
• Select the action you need, such as "Make changes to a thing," "Delete a thing," or "Schedule an API workflow on a list" for bulk actions.

    Make Changes to a Thing     This is a powerful action that allows you to modify existing data. Here’s how to use it for data cleanup:  

• Select "Make changes to a thing."
• Specify which data type you want to change.
• Add constraints and make the necessary changes to specific fields (e.g., trimming whitespace, converting to uppercase).

    Delete a Thing for Data Cleanup     To remove unwanted or redundant data:  

• Select "Delete a thing."
• Specify the data type and the particular item you wish to delete (you might need to use a search function to identify duplicates).

    Schedule an API Workflow on a List     For bulk data cleanup operations:  

• Go to the Backend Workflows section.
• Create a new API endpoint that includes the necessary cleanup actions.
• Use "Schedule API Workflow on a List" to apply these actions to a list of items in your database.

    Testing and Debugging     Always test your workflows thoroughly to ensure they perform the intended operations without any errors. Use debugging tools available in Bubble.io to monitor the execution of your workflows.  

• Go back to the app's preview mode.
• Trigger the workflows manually or wait for automatic triggers.
• Check the database for expected changes.
• Use the Step-by-step and Logs features under the Debugger to identify and rectify any issues.

    By following these steps, you can efficiently automate data cleanup tasks in Bubble.io, keeping your database clean and optimized with minimal manual intervention.
