Why Use a Script for Bulk Updates?

Imagine you need to update the status of all your records or adjust a field value for a large dataset. Doing this manually:

• Takes too much time.
• Increases the chance of errors.
• Gets repetitive and tedious.

Using a script solves these issues by automating the updates. Airtable’s Scripting app allows you to write JavaScript code to make changes quickly and accurately.

Getting Started: Setting Up the Scripting App

Before we write and run the script, you’ll need to set up the Airtable Scripting app. Here’s how:

1. Open your Airtable base.
2. Click on the “Apps” button in the upper right corner.
3. Click “Add an app.”
4. Search for “Scripting” and add it to your base.
5. Open the Scripting app, and you’re ready to write and run your script.

The Script: How It Works

Here is the script we’ll be using:

// Replace with your table name
const tableName = "YourTableName";

// Replace with the field name(s) you want to update
const fieldToUpdate = "YourFieldName";
const newValue = "New Value"; // Replace with the desired value

// Get the table
let table = base.getTable(tableName);

// Fetch records to update
let query = await table.selectRecordsAsync();
let records = query.records;

// Prepare an array for batch updating
let updates = records.map(record => ({
    id: record.id,
    fields: {
        [fieldToUpdate]: newValue
    }
}));

// Airtable API restricts batch size to 50
while (updates.length > 0) {
    await table.updateRecordsAsync(updates.slice(0, 50));
    updates = updates.slice(50);
}

output.text("Bulk update completed!");

Breaking Down the Script

Let’s understand how this script works step by step.

1. Define the Table and Field
   • Replace YourTableName with the name of your table.
   • Replace YourFieldName with the name of the field you want to update.
   • Replace New Value with the value you want to apply to all records in that field.
2. For example, if you want to set all records’ status to “Complete,” the newValue should be "Complete."
3. Access the Table
   • let table = base.getTable(tableName); retrieves your specified table in the base.
4. Fetch Records
   • await table.selectRecordsAsync(); gets all the records in the table so we can process them.
5. Prepare the Updates
   • updates is an array where each entry specifies the record ID and the field value to update.
6. Batch Updates
   • Airtable limits bulk updates to 50 records at a time. The script processes records in batches using a while loop to ensure this limit isn’t exceeded.
7. Run the Updates
   • The updateRecordsAsync function updates each batch of records until all records are processed.
8. Output Confirmation
   • Once all records are updated, the script outputs “Bulk update completed!”

How to Run the Script

1. Copy the script and paste it into the Scripting app in Airtable.
2. Replace the placeholders (YourTableName, YourFieldName, and New Value) with your actual table and field details.
3. Click “Run” to execute the script.
4. Watch as your records are updated in seconds!

Example Use Case

Let’s say you have a table named “Tasks” with a field called “Status.” You want to mark all tasks as “Complete.” Here’s how the script would look:

const tableName = "Tasks";
const fieldToUpdate = "Status";
const newValue = "Complete";

let table = base.getTable(tableName);
let query = await table.selectRecordsAsync();
let records = query.records;

let updates = records.map(record => ({
    id: record.id,
    fields: {
        [fieldToUpdate]: newValue
    }
}));

while (updates.length > 0) {
    await table.updateRecordsAsync(updates.slice(0, 50));
    updates = updates.slice(50);
}

output.text("Bulk update completed!");

Tips

• Test with a small dataset first to ensure the script works as expected.
• Back up your Airtable base before running the script, especially if you’re making significant changes.
• Use clear and descriptive names for your table and fields to avoid errors.
