Switch Automate

This workflow is ideal for:

• Data Analysts: Individuals who need to automate the extraction of data from PDF files and update records in Airtable without manual intervention.
• Developers: Those looking to integrate Airtable with other applications and streamline data processing workflows.
• Business Owners: Entrepreneurs who require efficient data management solutions to enhance productivity and reduce errors in data entry.
• Research Teams: Groups needing to extract specific information from documents for analysis and reporting purposes.

This workflow addresses the challenge of manually extracting data from PDF files and updating corresponding records in Airtable. It automates the process of:

• Receiving updates from Airtable via webhooks.
• Extracting relevant data from uploaded PDF files.
• Populating fields in Airtable based on dynamic prompts, ensuring timely and accurate data updates.

1. Webhook Trigger: The workflow starts when a specific event occurs in Airtable (e.g., a row or field is updated).
2. Parse Event: The event data is parsed to determine the type of update (e.g., row.updated, field.created, or field.updated).
3. Fetch Table Schema: The schema of the Airtable base is retrieved to understand the structure of the data and the fields that need updating.
4. Filter Valid Rows: The workflow filters out rows that do not have valid input fields to optimize processing.
5. Extract File Data: The relevant PDF file is fetched based on the row's data.
6. Data Extraction: The content of the PDF is extracted using the ExtractFromFile node.
7. Dynamic Prompt Generation: For each field that requires updating, a prompt is generated based on its description, and the extracted data is processed using an AI model (LangChain).
8. Update Airtable Records: The extracted data is used to update the corresponding records in Airtable, ensuring that all relevant fields are populated correctly.
9. Looping Mechanism: The workflow includes looping mechanisms to handle multiple records efficiently, ensuring that updates are made for all applicable rows.
