Python - Example Usage



Convert a simple RTF string to plain text:


---------------------------------------------------------------------------------------
``
from rtf_converter import rtf_to_txt

Sample RTF text

rtf_text = r"{\rtf1\ansi\ansicpg1252\deff0\deflang1033{\fonttbl{\f0\fswiss\fcharset0 Helvetica;}}{\colortbl ;\red255\green0\blue0;}\pard\tx720\tx1440\tx2160\tx2880\tx3600\tx4320\tx5040\tx5760\tx6480\tx7200\tx7920\tx8640\ql\qnatural\pardirnatural\f0\fs24 \cf0 Hello, World!}"

Convert RTF to plain text

plain_text = rtf_to_txt(rtf_text)
print(plain_text) # Output: Hello, World!
``
---------------------------------------------------------------------------------------

Python - Example Usage #2



Convert an RTF File to Plain Text


Read file from the disk, convert its content to plain text using the rtf_to_txt function, and then save the result to a new text file:


---------------------------------------------------------------------------------------
`
from rtf_converter import rtf_to_txt

Read RTF file

with open('sample.rtf', 'r', encoding='utf-8') as file:
rtf_content = file.read()

Convert RTF content to plain text

plain_text = rtf_to_txt(rtf_content)

Save plain text to a new file

with open('output.txt', 'w', encoding='utf-8') as file:
file.write(plain_text)

print("RTF has been successfully converted to plain text and saved as output.txt.")
`
---------------------------------------------------------------------------------------






Python - Handling RTF Conversion Errors



In case the RTF content is not formatted correctly, the rtf_to_txt function might raise an exception. Here is how you can handle such errors gracefully:


---------------------------------------------------------------------------------------
`
from rtf_converter import rtf_to_txt

Sample RTF text (potentially incorrect format)

rtf_text = r"{\rtf1\ansi\Hello, World!}"

Attempt to convert RTF to plain text

try:
plain_text = rtf_to_txt(rtf_text)
print(plain_text)
except Exception as e:
print("An error occurred during the conversion:", str(e))
`
---------------------------------------------------------------------------------------


JavaScript - Example Usage



Convert a simple RTF string to plain text:


---------------------------------------------------------------------------------------
`
// Start test server (http-server)
// Save test javascript file as a module (.mjs)
// Import the rtfToTxt function from the rtf-converter npm package
import { rtfToTxt } from './node_modules/rtf-converter/rtf_converter.js';

// Sample RTF text
var rtfText = "{\\rtf1\\ansi\\ansicpg1252\\deff0\\deflang1033{\\fonttbl{\\f0\\fswiss\\fcharset0 Helvetica;}}{\\colortbl ;\\red255\\green0\\blue0;}\\pard\\tx720\\tx1440\\tx2160\\tx2880\\tx3600\\tx4320\\tx5040\\tx5760\\tx6480\\tx7200\\tx7920\\tx8640\\ql\\qnatural\\pardirnatural\\f0\\fs24 \\cf0 Hello, World!}";

// Convert RTF to plain text
var plainText = rtfToTxt(rtfText);
console.log(plainText); // Output: Hello, World!
`
---------------------------------------------------------------------------------------






JavaScript - Example Usage #2 (With error handling)



Convert an RTF File to Plain Text


Read file from the disk (or fetch from a server), convert its content to plain text using the rtfToTxt function, and then save the result to a new text file:


---------------------------------------------------------------------------------------
`

















RTF Converter

Convert RTF to Text

// Import the rtfToTxt function from the rtf-converter npm package
import { rtfToTxt } from './node_modules/rtf-converter/rtf_converter.js';

// Function to handle the conversion process
function convertRTF() {
var fileInput = document.getElementById('rtfFile');
var file = fileInput.files[0];
if (!file) {
alert('Please select an RTF file to convert.');
return;
}

// Read the RTF content from the uploaded file
var reader = new FileReader();
reader.onload = function(event) {
var rtfContent = event.target.result;

// Convert RTF content to plain text using the rtfToTxt function
var plainText = rtfToTxt(rtfContent);

// Save plain text to a new file
var blob = new Blob([plainText], { type: 'text/plain' });
var link = document.createElement('a');
link.href = window.URL.createObjectURL(blob);
link.download = 'output.txt';
link.click();

console.log("RTF has been successfully converted to plain text and saved as output.txt.");
};
reader.readAsText(file);
}

// Make the convertRTF function globally accessible so that it can be called from the HTML file
window.convertRTF = convertRTF;
`
---------------------------------------------------------------------------------------







PHP - Example Usage



Convert a simple RTF string to plain text:


---------------------------------------------------------------------------------------
`
error_reporting(E_ALL);
ini_set('display_errors', 1);

require_once 'vendor/autoload.php';

use RtfConverter\RtfConverter;

$rtfText = "{\\rtf1\\ansi\\ansicpg1252\\deff0\\deflang1033
{\\fonttbl{\\f0\\fswiss\\fcharset0 Helvetica;}{\\f1\\fswiss\\fcharset0 Arial;}}
{\\colortbl ;\\red255\\green0\\blue0;\\red0\\green0\\blue255;}
Hello, {\\f1\\b World}! This is {\\i italic} text. The — dash and the – dash are different.
‘ Quotes ’ are special too. Unicode: \\u8364 is the Euro symbol.
Nested {\\b\\i bold and italic} text. Here's a list:
\\list\\listtemplateid1\\listhybrid
{\\listlevel\\levelnfc0\\leveljc0\\levelfollow0\\levelstartat1\\levelspace0\\levelindent0
{\\*\\levelmarker\\fi-360\\li720\\jclisttab\\tx720 }{\\leveltext\\leveltemplateid1'\\uc0\\u8226 ;}
{\\levelnumbers\\leveltemplateid2'\\u-3999 \\u8197 ;}}Hello from nested list!
}";



echo "Before conversion\n";
$plainText = RtfConverter::rtfToTxt($rtfText);
echo "After conversion:\n";
echo $plainText . "\n";
echo "Type of output: " . gettype($plainText) . "\n";
echo "Length of output: " . strlen($plainText) . "\n";
?>
