Automate ETL over Financial Data 📊 Most real-world financials are not “database-shaped”, and requires a ton of human effort to manipulate/copy an Excel sheet into structured formats for analysis. We recently launched LlamaSheets - a specialized AI agent that automatically structures your Excel spreadsheet into a 2D format for analysis. There are so many use cases for Excel, and accounting is a huge subcategory here. Check it out: https://www.llamaindex.ai/blog/announcing-llamasheets-turn-messy-spreadsheets-into-ai-ready-data-beta

We wrote a tutorial on extracting massive structured tables from documents 📃 Using naive LLM structured output for document extraction fails if the number of output tokens is large - the LLM will end up dropping or hallucinating results. A lot of documents are basically rendering massive tables in PDF form, like this Blue Shield document showing network coverage across 380+ CA hospitals. We created a new mode in LlamaExtract that lets you extract every single row from this document with 100% accuracy. This lets you: * ETL it into a structured database * Do structured queries over it. * And more!

RT LlamaIndex 🦙 POV: You're building an agent and it keeps giving weird answers because your PDF parsing is broken 🫠 This is a great walkthrough by @mesudarshan showing exactly how to use LlamaParse to fix this—from basic setup through advanced configs. The video walks through: · Why most PDF parsers fail on complex layouts (tables, charts, multi-column text) · Using the LlamaCloud playground to experiment · Real demo: parsing "Attention Is All You Need" paper with different settings · Cost-effective vs agentic vs agentic plus modes—when to use each · Preset configs for invoices, scientific papers, forms (they tune the parsing prompts for you) · Advanced options: OCR, language selection, choosing your LLM (Sonnet, GPT-4, etc.) · Saving custom configs so you don't have to re-tune for similar docs https://youtu.be/mUHPPBbumIs?si=sWBDIoR9376wYP7R Original tweet: https://x.com/llama_index/status/1994452235754029426

We launched a new API today to let you parse any Excel sheet in a structured table. Take a look at this example on core production costs 🌽: 1️⃣ The table is located at the center of the sheet with headers, footnotes, and a hierarchical column layout 2️⃣ We get back a structured table with summarization, along with parsed row/column representations This lets you directly run text-to-pandas/SQL over this data if you’re building an AI agent, or do ETL yourself over it.

Introducing LlamaSheets 🦙 - a specialized AI agent that can convert complex spreadsheets into normalized, structured data. Excel files are arbitrarily complicated - they contain semi-structured numerical data, complex formatting, visual hierarchies. A lot of Excel files “look like tables” to the human eye but are impossible to parse as actual tables if you tried to read the raw cell values. Parsing Excel files requires a completely different stack from parsing any other document format. We’ve been hard at work over the past few months doing applied research on understanding Excel files. The result is we’ve created a powerful algorithm to help identify, segment, and output structured tables - and this includes preserving multi-level row and column hierarchies. The output is a structured dataframe that you can directly run queries over, OR feed it as a tool to an upstream AI agent. Any AI agent will have a much easier time understanding these structured values vs. trying to write code (e.g. openpyxl) to manipulate the raw Excel values - it raises accuracy and reduces cost. This was a teamwide effort and huge shoutout to everyone who contributed to this. Check out our video, blog, docs, and signup below!

We've created a specialized agent that lets you extract out every single row from super complex embedded tables ✂️, with super high-accuracy. Simply define a simple schema with natural language containing the elements you want to extract, and upload your doc(s). If you try this by just prompting an LLM, you are going to run into hallucinations and/or dropped output - the output token space is super large and the raw model has a high probability of failing.

It's pretty clear that AI agents can inhale documents and perform knowledge work. It's also pretty clear humans need to be able to observe this process to prevent things from going off the rails. One of the biggest benefits towards orchestrating document workflows through code (vs. a no-code builder like traditional RPA tools) is native integrations with OpenTelemetry and all the wonderful AI observability tools out there. This is exactly what LlamaAgents provides. This is super important because documents are inherently big containers of unstructured data. Workflows transform this mess of tokens into structured outputs over time. Trying to manually inspect everything is a nightmare. These integrations allow you to dump the full LLM traces into any supported observability tool out there, giving both non-technical and technical users extremely granular insights into what's going on, and allowing steerability in the case of unexpected outputs.

I did some weekend reading into the recently released OlmOCR2 model by @jakepoznanski et al. 📄🔎 A cool insight here is that you can scalably do RL on your document parsing model (specifically RLVR) in an automated fashion - without needing humans for feedback or creating the reward function for each document. The authors use Sonnet to generate an HTML scaffold to then generate tailored unit tests for each document. The unit tests themselves are deterministic, but the generation is through an LLM. The parsed outputs are scored against the unit tests, which creates feedback signals for the model. This is nice because: - Manually generating parsed ground-truth for documents is a pain in the ass - Manually generating tests for documents is also a pain in the ass - So scaling up data and signals for document understanding has been painful Blog + paper: https://allenai.org/blog/olmocr-2 From our side, we’re constantly benchmarking all the latest OCR models in our LlamaParse pipeline.

This past week the entire @llama_index team got together in Mexico City 🇲🇽 We reaffirmed our focus: we’re all in on building AI agents to solve document processing and workflows 📑🤖 We are not building simple LLM framework abstractions. We are building incredibly deep OCR technology across multiple price points to unlock content from any unstructured document. Most importantly, we ate a ton of tacos 🌮🌮🌮🌮 We have a ton of releases slated from now until EOY, stay tuned! Also we’re hiring: https://www.llamaindex.ai/careers Until next time CDMX :)

We’ve created a specialized agent tuned for row-level table extraction 🧩🤖 A lot of document workflows involve converting a complex table in a .pdf/.docx file into an Excel spreadsheet. Oftentimes this work is done manually. We created a mode in LlamaExtract that only deals with table extraction. Simply define the schema you want for each row, and the agent will extract out all rows from every table corresponding to this schema! It can not only populate the row context, but also the global table context. Check it out in LlamaCloud: https://cloud.llamaindex.ai/

Our new bounding box approach in LlamaParse gives you clean bounding boxes while preserving clean reading order of the text through agentic reconstruction. The issue with traditional parsing methods is that the quality of the output is directly dependent on the layout detector - if the predicted boxes are wrong / in the wrong sequence, then your output is garbled. Here we use LLMs to reconstruct the entire semantic flow of the text, but still allow bounding box processing in parallel for additional metadata! Now available in LlamaParse: https://cloud.llamaindex.ai/

RT LlamaIndex 🦙 Here's a common scenario: Your finance team gets emails all day with invoices from partners and expense reports from employees. Each one needs different handling. Invoices need acknowledgment and payment scheduling. Expenses need budget validation before approval etc. In this example we build an agent that automatically triages incoming emails with attachments, extracts the right information, and takes appropriate action. Our approach uses three of our tools working together: 1️⃣ LlamaClassify handles the first decision point. It looks at each attachment and determines: is this an invoice that needs to be paid out to a partner, or an expense that needs reimbursement? It also provides reasoning for the decision. 2️⃣ LlamaExtract does the heavy lifting on data extraction. We create two specialized agents with different schemas for invoices vs expenses. 3️⃣ Agent Workflows orchestrates the entire process. It connects classification to extraction to business logic: in this case, checking expenses against a budget threshold and generating appropriate email responses via LLM. Classify incoming documents → extract relevant data → apply business rules → take action. Need to add a new document type? Add a classification rule and an extraction schema. Need different business logic? Modify the workflow steps. The components stay the same.

grep AND semantic search is all you need The fact that coding agents can access CLI commands makes them way better at search than standard retrieval. with grep/read/cat operations you can dynamically load different chunks of data and traverse complex directories. Obviously the even better answer is to just combine the two. Combine grep with semantic search. If you want to DIY this, check out `semtools`! We've built a simple lightweight, index-free engine that lets you run semantic search over any directory as a CLI command. Easily give it to your favorite coding agent e.g. Claude Code / Cursor to run. https://github.com/run-llama/semtoolsCursor: Semantic search improves our agent's accuracy across all frontier models, especially in large codebases where grep alone falls short. Learn more about our results and how we trained an embedding model for retrieving code. Link: https://x.com/cursor_ai/status/1986124270548709620

semtools is the easiest way to let your Claude Code / Cursor become an analyst over 1k+ PDF docs. It just adds two CLI commands: `parse`, `search`. Install it to ~/.zshrc and add it to your http://CLAUDE.md. Any coding agent can still choose to use grep, but now they get access to semantic search.

RT LlamaIndex 🦙 Last week, we teamed up with @MongoDB to break down one of the most persistent challenges in production AI systems: turning messy, real-world documents into reliable insights. Enterprise documents don't come in neat, uniform packages. Invoices, SEC filings, reports—they all have irregular layouts, embedded tables, images, and context that traditional text extraction just can't handle. In this session, we walked through a complete document processing workflow that works at scale: LlamaParse acts as an agentic parsing tool that understands document structure—not just text extraction. It handles complex layouts, preserves table formatting, and extracts images with context. It outputs clean markdown that LLMs can work with.

Haiku 4.5 is better than GPT-5 at document OCR over tables 📋 Better reasoning doesn’t correlate to visual understanding 💡. I fed the NYC MTA timetable as screenshots into both GPT-5 and Haiku 4.5. - (Left) GPT-5 ignores the spaces between table values - (Right) Haiku almost perfectly reconstructs the table including spaces in between. The extra columns don’t materially impact the correctness of the results. Haiku is shaping up to be a great lightweight contender for document parsing.
