Table Extractor Powered By Claude Tool Use and Reflex

Prerequisites

First you need to have an Anthropic API key. Get yours by signing up at Anthropic.

Requirements

The following packages are required to run the code:

reflex==0.4.6
anthropic
Pillow

How It Works

Follow the Claude API Tool Use docs and define a extract_table function that takes an image file and return an extract table as a list of lists.

How to Run the App

Export this as an environment variable:

export ANTHROPIC_API_KEY=your_api_key

This app is based on Reflex framework. In the top level directory (this directory has a file named rxconfig.py), run the following commands to run the app:

reflex init
reflex run

Also check out Reflex Documentation to build/run/host your own app.

Limitations

  1. Right now, only support certain image types supported by Anthropic messaging API, no PDFs.
  2. Only the first table in the image is returned. Experimented with multiple tables and the results were not as good.
  3. The return table is a plain text representation. Best returned result is a json encoded string of the table, so less post processing code.
