Overview

ExtractTable - API to extract tabular data from images and scanned PDFs

The motivation is to make it easy for developers to extract tabular data from images or scanned PDF files without worrying about the table area, column coordinates, rotation et al.

Prerequisite

API Key: All requests to ExtractTable are authorized by an API Key. FREE credits here. The same API Key can also be used for conversions on the browser at Web Pro.

Installation

pip install -U ExtractTable

Basic Usage

Ok, enough selling. Let the ease in coding do the talk, and the output encourages you to buy credits; put that timer on and count the LOC.

from ExtractTable import ExtractTable
et_sess = ExtractTable(api_key=YOUR_API_KEY)        # Replace your VALID API Key here
print(et_sess.check_usage())        # Checks the API Key validity as well as shows associated plan usage 
table_data = et_sess.process_file(filepath=Location_of_Image_with_Tables, output_format="df")

# To process PDF, make use of pages ("1", "1,3-4", "all") params in the read_pdf function
table_data = et_sess.process_file(filepath=Location_of_PDF_with_Tables, output_format="df", pages="all")
