Text Extraction from MS Office and PDF files

Yet another library to extract text from MS Office (docx, pptx, xlsx) and PDF (pdf) files.

Similar libraries

There are other great libraries that do the same job and have inspired this project, such as:

• any-text
• officeparser
• textract

How this is different from other text extraction tools

• Parses file based on mime type, not file extension
• Does not spawn a child process to use a tool installed on the device
• Reads and returns text from file if it is a simple text file

Libraries used

This module uses some amazing existing libraries that perform better than the ones that originally existed in this module, and are therefore used instead:

• pdf-parse, for parsing PDF files
• xlsx, for parsing MS Excel files

This module also uses:

• xml2js - to convert the MS Office XML files into JSON
• js-yaml - to convert JSON into YAML
• file-type - to detect the mime type of files
• decompress - to unzip files
• read-chunk - to read chunks of data from large files

A big thank you to the contributors of these projects.

Installation

To use this in an npm project, simply type in:

npm install office-text-extractor

Usage

// Importing the library:

// CommonJS import
const extractText = require('office-text-extractor');

// ES import
import extractText from 'office-text-extractor';

// Extracting text:

// Async-await way
const text = await extractText('path/to/file');
console.log(text);

// Promise way
extractText('path/to/file');
  .then((text) => {
    console.log(text);
  })
  .catch((err) => {
    console.error(err);
  })

Tests

To run tests (using Ava), type the following:

npm test

Todos
