• Head over to the base you want to work on in Airtable.
• Look for the “Apps” button (or “Blocks” if you're using an older version) in the top right corner and click it.
• Hit the “+ Add an app” button.
• Search for the “Scripting” block and add it to your base.

• After adding the scripting block, click on it to open it up.
• You'll see an editor where you can write and run your scripts.

• Take a good look at the data you want to clean. Figure out what exactly needs to be cleaned up (like removing empty rows, trimming whitespace, or formatting dates).

• In the scripting editor, start writing your script. Here's an example of a script that removes rows with empty fields and trims whitespace from text fields.

Example script:

// Select the table to clean
let table = base.getTable("Your Table Name");
let query = await table.selectRecordsAsync();

// Iterate through each record
for (let record of query.records) {
    // Check for empty fields and trim whitespace
    let updates = {};
    let hasEmptyFields = false;
  
    for (let field of table.fields) {
        let value = record.getCellValueAsString(field.name);
      
        // Check for empty fields
        if (!value) {
            hasEmptyFields = true;
            break;
        } else {
            // Trim whitespace
            updates[field.name] = value.trim();
        }
    }
  
    // Remove the record if there are empty fields
    if (hasEmptyFields) {
        await table.deleteRecordAsync(record.id);
    } else if (Object.keys(updates).length > 0) {
        // Update the record with trimmed whitespace
        await table.updateRecordAsync(record.id, updates);
    }
}

output.text("Data cleaning complete!");

• Click the “Run” button in the script editor.
• The script will run and clean the data based on the logic you provided.

• Check the table to make sure the data cleaning worked as expected.
• Note any records that might not have been cleaned properly and tweak the script if needed.

• If you need to clean data often, save the script for future use.
• Think about setting up an automation to run the script on a schedule or when certain events happen in Airtable.
