Turn attached PDFs in Airtable into clean field values without manual typing. When a row changes or a field is added or updated, the flow reads the PDF, runs prompts from the field descriptions, and writes results back to the record. It fits teams that collect files in Airtable and need fast, accurate data entry at scale.

The run starts from an Airtable webhook event and routes by event type. It fetches the table schema to read each field description as a dynamic prompt. For row updates, it filters to rows that have an input file and only targets empty fields to avoid extra work. The file is downloaded, the text is extracted from the PDF, and an AI model generates a short answer that matches the field type. Batching nodes handle rows one by one so users see updates quickly. A second path updates every row for a field when a column is created or changed.

You need an Airtable Personal Access Token and an OpenAI key. Add an input column for file uploads, publish the workflow, and run the provided steps to register Airtable webhooks. Expect large time savings on contract intake, resume reviews, invoices, and form uploads. Most teams cut manual entry and improve consistency while keeping the process inside Airtable.

• Event router sends row changes and field changes down the right path for targeted updates
• Schema fetch reads field descriptions and turns them into dynamic prompts for AI
• Row filter only processes records that have an input file to save time and credits
• Batch loops update items one at a time so changes appear quickly in Airtable
• PDF text extraction pulls content from attachments before sending to the AI model
• AI prompt uses the field description and expected type to generate short, usable values
• Selective field updates skip columns that already have values to avoid reprocessing
• All records path updates every row when a field is created or changed for full backfill
• Manual test trigger helps validate the flow before going live
• Record update writes results back to Airtable using the row id from the webhook

• Reduce manual work from hours per batch to minutes by reading PDFs and filling fields automatically
• Automate up to 80 percent of repetitive data entry by using field descriptions as prompts
• Improve data quality by limiting human copy and paste errors and enforcing field types
• Handle thousands of rows with batching and event routing without blocking your table
• Connect Airtable and OpenAI so files become structured records with minimal setup

1. Import the template into n8n: Create a new workflow in n8n > Click the three dots menu > Select 'Import from File' > Choose the downloaded JSON file.
2. You'll need accounts with Airtable and OpenAI. See the Tools Required section above for links to create accounts with these services.
3. In the n8n credentials manager, create an Airtable credential using a Personal Access Token. Name it clearly, set the token from your Airtable account, and save.
4. Create an OpenAI credential. Choose API Key, paste your key from the OpenAI API page, give it a clear name, and save.
5. Open the Airtable related nodes and select your Airtable credential in the Credential to connect with dropdown.
6. Open the OpenAI nodes and select your OpenAI credential in the Credential to connect with dropdown.
7. In your Airtable base, add an attachments field that will hold the input file. Make sure the field name matches the value used in the Get Input Field step.
8. Publish the n8n workflow so the webhook URL is active. Copy the production URL from the Airtable webhook node if needed.
9. Run the included mini flow to register Airtable webhooks. Use the manual trigger to execute the Records Changed and Fields Changed webhook steps and confirm they return success.
10. Click Execute workflow in n8n and upload a small test PDF to a record in Airtable. Watch the execution, confirm the file is downloaded and text is extracted, and check that fields update.
11. If updates do not appear, verify the event type routing, confirm the input field has a file, and check that field descriptions contain clear prompts.
12. For large tables, start with the minimal rows path first. Use Airtable filters to limit records until you confirm performance.
