Data & Analytics Workflows

This template can be used to **upload the files in your Google Drive** to an **[InfraNodus knowledge graph](https://infranodus.com)**. The InfraNodus graph will then reveal the **main topics** and **ideas** in your collection of documents and show the **content gaps** in them. You can also use the **built-in AI** to converse with the documents.  You can also access the InfraNodus Graphs via its **GraphRAG API** to reuse them in your other n8n workflows for high-quality content retrieval and knowledge base optimization. The template showcases the use of multiple n8n nodes and processes: - Extracting documents from a Google Drive folder - Text extraction - Optional: high-quality PDF conversion using [ConvertAPI](https://convertapi.com?ref=4l54n) - [InfraNodus knowledge graph](https://infranodus.com) generation **Note**: If you want to **Sync your Google Drive** to an InfraNodus graph, check out our other workflow. ## How it works Here's a description of this workflow step by step: - Find all the files in a specific Google Drive folder - For each file found: reiterate the workflow and - Identify the type of the file (X, PDF, Markdown) - For X and Markdown files, extract the text data - For PDF files, use a special PDF to text converter to extract the text data. (Optional: using [ConvertAPI](https://convertapi.com?ref=4l54n) for better quality PDF conversion) - Forward everything to the InfraNodus `graphAndStatements` [API endpoint](https://support.noduslabs.com/hc/en-us/articles/13605983537692-InfraNodus-API-Access-Points) with the `name` of the new graph, the `text` field with the text data, the text settings, and `doNotSave=false` to create a new graph - Reiterate through another file. ## How to use You need an [InfraNodus GraphRAG API account and key](https://infranodus.com/use-case/ai-knowledge-graphs) to use this workflow. - Create an InfraNodus account - Get the API key at [https://infranodus.com/api-access](https://infranodus.com/api-access) and create a Bearer authorization key for the InfraNodus API nodes. - Use that API key to set up authorization for the InfraNodus tool in the workflow. - If you want to upload the files to an existing graph, you should copy its name from InfraNodus. Otherwise, you can specify any name you want. ## Requirements - An [InfraNodus](https://infranodus.com/use-case/ai-knowledge-graphs) account and API key - A Google Drive account and authorization (you will need to set it up via Google Cloud using the n8n instructions provided in the Google Drive node). ## Customizing this workflow You can use Dropbox instead of Google Drive. You can also modify this workflow slightly to make it sync with a Google Drive when new files appear in it.
