Llamaindex document loader. A Document is a generic container around any data source - for instance, a PDF, an API output, or retrieved data from a database. Data from various sources (like text files, PDFs, or web pages) is processed by appropriate LlamaIndex Readers (e. , SimpleDirectoryReader, SimpleWebPageReader) to create standardized Document objects containing text and metadata. May 30, 2025 · This tutorial covers LlamaIndex 0. TS supports easy loading of files from folders using the SimpleDirectoryReader class. Data connectors ingest data from different data sources and format the data into Document objects. Supported file types By default SimpleDirectoryReader will try to read any files it finds, treating them all as Apr 21, 2025 · What Are Document Loaders? Document loaders take your files — like a CSV table, a website, or a PDF — and convert them into plain text that a RAG system can understand. They can be constructed manually, or created automatically via our data loaders. LlamaIndex simplifies connecting large language models (LLMs) to external data by organizing documents into searchable indexes. 9. Once you have loaded Documents, you can process them via transformations and output Nodes. Some of these are Jun 30, 2023 · LlamaIndex is a toolkit to augment LLMs with your own (private) data using in-context learning. To achieve that it utilizes a number of connectors or loaders (from LlamaHub) and data structures (indices) to efficiently provide the pre-processed data as Documents. Loading using SimpleDirectoryReader SimpleDirectoryReader SimpleDirectoryReader is the simplest way to load data from local files into LlamaIndex. LlamaIndex. Documents can either be created automatically via data loaders, or constructed manually. 0’s new document processing features with practical examples. Mar 16, 2024 · Simply put a document is a container with data in it, data can be from a text document to data from databases. g. The key to data ingestion in LlamaIndex is loading and transformations. By default, all of our data loaders (including those offered on LlamaHub) return Document objects through the load_data function. For production use cases it's more likely that you'll want to use one of the many Readers available on LlamaHub, but SimpleDirectoryReader is a great way to get started.

To retrieve documents using LlamaIndex, you’ll need to structure your data, build an index, and query it using natural language or specific parameters. ai/l/file-pdf), but most examples I found online were people using it with OpenAI's API services, and not with local models. . A Document is a collection of data (currently text, and in future, images and audio) and metadata about that data. You’ll learn to implement advanced parsing methods, optimize document chunking, and build more effective RAG applications. It is a simple reader that reads all files from a directory and its subdirectories and delegates the actual reading to the reader specified in the fileExtToReader map. It takes care of selecting the right context to retrieve from large knowledge bases. Main components of documents are its text, related metadata and relationships Documents / Nodes Concept Document and Node objects are core abstractions within LlamaIndex. The way LlamaIndex does this is via data connectors, also called Reader. fwqu dskwf cbza yqlwbw ttw egjm szpy cryhvn wmjt onau
