Your job as a web developer is to develop web applications that are reliable. Coding and debugging errors, as well as managing servers, are also essential. It is, fortunately, possible to simplify the entire web development process without compromising its quality by using web development and utilities tools. In addition to improving the performance of your web applications, these tools often include automation and security features.

Nonetheless, it can be challenging to decide which web application development tool is right for you since numerous tools are being developed and updated regularly. Listed below are the best utility tools for beginners, intermediate, and advanced developers.

Best Online Utility Tools For Developers

A set of online utility tools are available on LambdaTest, a cloud-based platform where you can test your website and mobile applications. It also supports different frameworks for web and mobile automation testing frameworks like Selenium, Cypress, Playwright, Appium and more.

Here is a list of the best utility tools that LambdaTest offers.

1. Find and Replace String

With find and replace, you can search for substrings. This can be done in your browser and then you can replace them with new strings. You can also use regular expressions to find matches to replace these strings.

The input field should be filled in with the value that you are trying to find. When the given input is found, mention the value that you want to replace. In the end, you must specify both the find and replace values. With just a single click, you can replace the values automatically based on the inputs you provide.

2. HTML Escape

In HTML code, special characters are represented by HTML escaping. As an example, the HTML markup language has a special meaning for  less than symbol >. A string can be converted into HTML entities or HTML entities converted to plain text with this tool.

If your browser encounters one of these characters, a page may display incorrectly. We must escape special characters when storing raw HTML in databases or variables to prevent them from being confused with markup. Using entities, HTML replaces special characters and symbols that have special meanings in HTML—such as & < > ” ‘ .

3. HTML Unescape

Ascii characters are replaced with special HTML characters by using the html.unescape() method to convert them into HTML script. This tool will convert HTML entities to a string or convert plain text to HTML entities.

HTML code is often converted to its numeric equivalent when it is saved in a database or a variable; the code is converted using special HTML reserved characters and their numerical equivalents defined in the HTML5. HTML Unescape replaces any HTML code of reserved HTML characters with its original character representation.

4. Difference Checker (String) online tool

Using a difference checker, you can simply compare two texts. Using LambdaTest’s Difference Checker, you can compare the contents of two files line by line in seconds. You just have to click on the Compare button after entering the two strings of text you wish to test for differences.

By comparing the first character in each string, the tool determines whether the first character is greater or smaller than the other.

5. Shuffled String

An output from this tool consists of a shuffled string generated from the given input using Fisher-Yates-Knuth algorithms. A new permutation of letters in the string with the same probability distribution is created by dividing the string into two parts and traversing each part repeatedly.

6. Shuffle Text Lines Tool

You can shuffle a number of lines using the Shuffle Text Lines tool online. On the basis of the given input, the Fisher-Yates-Knuth algorithm generates a shuffled textual output.

Input text lines are shuffled into random order by the text lines shuffler. This tool shuffles text lines to rearrange the order of lines in the given textual data. It is useful for creating randomized lists or making up riddles. To accomplish this, Fisher-Yates-Knuth is used.

Depending on the number of lines being shuffled simultaneously, the algorithm’s behavior changes. Every line in the file is treated separately, a random number from 1 to the number of lines in the file is generated, and that line is moved to the new position. There is no need to split the lines apart when doing this on several lines at once.

7. Sorting List Tool

A simple, browser-based tool that sorts items in lists and arranges them ascendingly. In order to sort items and analyze them in meaningful order, you can arrange them alphabetically or numerically. To determine the minimum and maximum deal closures in a month, you could order sales data according to revenue generated. By using this tool, you can sort out the lines given as input in ascending order based on the alphabetic or numerical order.

8. String Split Tool

A string of characters can be split into multiple strings with the help of this tool. A string can be split in several ways, such as using a comma between characters or splitting at spaces in the string. A single String can be broken or split into multiple Strings by the method split(), which returns an array of those Strings separated by delimiters. By passing a limit, we can limit the size of the returned array.

9. Text Lowercase Online

When you enter upper case letters into the text area, the lower case text tool will convert them to lower case letters. For most words except for words that begin sentences and proper nouns, lower case letters are typically used for most letters.

By using the Lowercase tool, all capital letters in the text area will be converted to small letters. In a word, lowercase letters are used for all letters except those that begin sentences or proper nouns. When you provide input, the tool will search for uppercase characters. A lower case character will be converted if an upper case character is found. The output will remain the same as the input if there is no upper case letter found.

10. Text Uppercase Online

Below you will find an uppercase text tool that allows you to change all lowercase letters to capital letters. The text needs to be copied and pasted into the text area below and clicked. All your text will be in uppercase, just like it was before.

Any text string can be converted into uppercase using the text uppercase converter. The lower text letters are changed to uppercase after passing the string. AS AN EXAMPLE, THIS TEXT IS UPPERCASED.

11. Text Repeater

There is no limit to how many times you can repeat a word in your text. Select how many times you want the text to appear by writing it or copying and pasting. Text repeater lets you repeat a string as many times as you specify. It is also called a Text Multiplier Tool. The string is printed on a new line each time it is repeated.

12. Text Rotater

A letter in a sentence can be rotated left or right using this tool. You can shift the text one character left by selecting the left option. This will result in the first letter ending up at the end of the string. You will see the letter from the end of the text moving to the front if you choose the right direction.

By rotating its first or last letter, the text rotator simply moves the string’s first or last letter. The first letter of the string is stored and printed at the end of the string when the string is rotated left. When rotating the string to the right, the tool prints the last letter of the string first, followed by the entire string.

13. Decimal to Roman Converter

Using this converter, you can convert any decimal number into a Roman numeral by pasting or typing it in the text box. In a decimal to roman number converter, the base value of the decimal number is compared to the roman numeral and a unique roman numeral is assigned to each place in the decimal number.

A comparison is made between the largest decimal base value and the base decimal value. Each time we print the roman numerals, we get the same result. Once the decimal number has been inserted, you will have a roman numeral.

14. Character Count

In order to determine how many characters (including spaces) there are in a string of text or numbers, programmers can use the character count. Then simply click Count after adding your string to the “Enter Any String” section. A character count (including spaces) for a given string will be provided by the free online tool.

15. Word Count

Word Counter makes it easy to determine how many words are in a text of any length. Press the count button after writing or copying the text. You will be able to see how many words are in that text block when you use this tool. Whenever you have a minimum or maximum word count for your writeup, this tool helps you achieve it accurately. By passing each letter separated by a space, the word counter counts the word as an increment counter. In the text box, you paste the text snippet and the algorithm takes care of the minor edge cases to calculate the word count.

16. Lines Count

A document or passage of text can be counted by using the free online Lines Count tool. Lines can be counted with or without blanks. You can check the quality of strings and documents using the Line Count tool. Furthermore, it allows developers to determine the effort required to write a program by measuring the code size. Lines Count can be used by pasting any string into the above given box and hitting “Count”. That’s it! You can find out how many lines there are in a string or text by using our online tool.

17. Sentence Count Converter

Any text snippet can be analyzed to see how many sentences it contains using the Sentence Counter. Press the count button after you write or copy and paste the text. You will be able to see how many sentences are contained within that text block by using the tool. When there is a minimum or maximum word count for any write-up, it helps you achieve the exact count or range of words.

As an increment counter, the sentence counter counts sentences by counting the indicators of sentence formation and termination, such as full stops, exclamation marks, and so on. Text snippets pasted into the text box are processed using an algorithm that handles edge cases.

18. URL Parse Online

Its purpose is to provide a quick way to break down URLs into their individual components, revealing key information such as the scheme, protocol, username, password, hostname, port, domain, subdomain, top-level domain, and query string. Splitting up the query string and decoding the parameters are taken care of by URL Parse Online.

19. Escape JSON

Parsing errors can be caused by characters that are not escaped by JSON Escape. The escaped versions of special characters such as quotes, newlines, and backslashes will be used instead. When you use escape characters, you can replace existing characters with new ones without throwing an error. Special escape sequences are used to escape characters in a UTF-8 encoded Unicode string. HTML text is rendered in a preformatted tag when you escape it to plain JSON with this utility.

20. Unescape JSON

By converting JSON strings to plain JSON, JSON Unescape makes it possible to display text enclosed in ‘pre’ tags. In most cases, any string that contains escape notation will be unwrapped by the parser when it is parsed. A pretty print or minification may also be applied to the code. By removing offending characters, Unescape JSON allows it to be parsed.

21. Extract Text from HTML online tool

Text can be collapsed using the collapse-whitespace option by removing all HTML tags and preserving the text structure. It is also possible to configure the “br” tag so that a new line is inserted into the generated output. The HTML file can contain various types of data or text. A HTML file consists primarily of tags containing text, images, and other data. A web page’s layout is formed by arranging these tags in a particular way.

22. Extract Text from JSON online tool

LambdaTest offers a free tool that converts JSON documents into text documents. Furthermore, it allows you to extract node text and tag names from JSON files.

It is possible to extract text from an JSON document using LambdaTest’s free online Extract Text from JSON tool. Only textual content between tags is left after removing all special characters. Simple details can be extracted from a JSON document using this tool. It allows you to make simple clicks instead of writing code if you don’t have any programming experience.

23. Extract Text from XML online tool

An XML document can be converted to a text document by using LambdaTest’s free online tool. Additionally, it allows XML documents to be extracted for tag names and node text.

It is possible to extract text from an XML document using LambdaTest’s free online Extract Text from XML tool. Textual content is left between tags after it removes all special characters. An XML document can be extracted using this tool. Because it works by clicking instead of writing code, it’s useful if you have no programming experience.

24. Strip HTML

This method converts text into binary data so that it can be transmitted by e-mail and HTML forms more easily. It is a function that lets you remove all HTML and PHP tags from a string, as well as a list of tags. Strip Tags (strips out all HTML and PHP tags from a string) is a function that lets you remove all HTML and PHP tags from a string.

Your website can now be protected from unwanted text displayed by visitors. It is possible for a forum user to post something like THIS SITE IS A SCAM! They can contact you if they are unhappy with their experience using your website. Your website would not display the user’s text, however, if you used this function.

25. JSON Validator

Formatting and validating JSON data is now easier than ever thanks to the JSON Formatter & Validator. There are no ads or popups on this JSON Validator by LambdaTest, which is free. It is the easiest and quickest method to test the validity of JSON data by loading it into a JObject or JArray and testing it against the JSON Schema using the IsValid(JToken, JsonSchema) method.
