Library to parse a pdf file and extract all the tables contained returning a json object.

pdf-tables-parser

Library to extract text tables from pdf files.

Background (why)

Sometimes your server has to retrieve information from pdf files E.g. financial reports, where the information is inside tables (rows, columns).

However there's no an easy way to extract this information from Nodejs applications. All the alterantives I tried need an extra processing to get the tables I wanted, so finally I decided to create one of my own.

Demo

You can test online the library here

Installation

$ npm install -g @pomgui/pdf-tables-parser

Usage

const
    { PdfDocument } = require('@pomgui/pdf-tables-parser'),
    fs = require('fs');

const pdf = new PdfDocument();
pdf.load('report.pdf')
    .then(() => fs.writeFileSync('report.json', JSON.stringify(pdf, null, 2), 'utf8'))
    .catch(err => console.error(err));
