Extract text from PDF and image using Vertex AI (Gemini) into CSV
Description
Extracting text from PDFs and images can be a tedious and time-consuming task. Many professionals find themselves manually entering data from scanned documents, which not only increases the likelihood of errors but also consumes valuable time that could be spent on more strategic tasks. This workflow addresses the frustration of manual data entry by automating the extraction process, allowing users to convert text from various document formats into a structured CSV file effortlessly.
The workflow operates using a series of interconnected nodes in n8n. It begins with the 'googleDriveTrigger' node, which detects new PDF or image files uploaded to Google Drive. Upon activation, it utilizes 'extractFromFile' to read the content of the files. The extracted text is then processed through 'lmChatGoogleGemini' for advanced text analysis. Following this, a 'switch' node determines the type of file, ensuring appropriate handling for PDFs versus images. Finally, the workflow utilizes 'convertToFile' to store the cleaned data as a CSV file back in Google Drive, enabling easy access and sharing.
This workflow is particularly beneficial for data analysts, researchers, and administrative professionals who deal with large volumes of documents. For instance, a data analyst could use it to extract text from research papers for data compilation. Similarly, administrative teams can automate the extraction of information from scanned invoices or forms, reducing the workload significantly. These use cases highlight how various teams can enhance productivity by automating document processing.
To get started with this template, you can access it through FlowEngine and deploy it directly to your n8n instance. Customization options are available, allowing you to modify the workflow to suit your specific needs, such as adjusting the file types or output formats. By utilizing this n8n automation, you can enhance your document processing capabilities without extensive coding knowledge.
