How Do I use a Custom Tool as a Document Loader

[WizKid1968]

Hey guys and gals,

I created an Airtable custom tool. The tool retrieves records from airtable table, but I'm having a hard time querying the data because it's too large, so I am wondering if there's anyway of splitting the data and storing the retrieved data in Pinecone? If anyone can help me creating a flow that can do this I would greatly appreciate it. Thanks in advanced.
