FREE ONLINE TOOLS FOR DEVELOPERS

I created this website to help developers by providing them with free online
tools. These tools include several formatters, validators, code minifiers,
string escapers, encoders and decoders, message digesters, web resources and
more.

I will add new tools on a regular basis, so be sure to add this site to your
bookmarks.

If you encounter a bug, I would very much appreciate that you send me an email
(freeformatter@gmail.com) that explains the nature of your bug. Please include
details like which browser version you're using and the steps to reproduce the
bug. Other comments are welcome.

Please "+1" and/or "Facebook Like" this site if you thought it was useful.

Update September 2020:
I am permanently removing the batch formatter as people have been abusing it in
too many ways.

Update September 2020:
I have updated the site to support IAT TCF 2.0 as it is required moving forward
to operate in Europe. Please consider disabling ad blockers for my site (or
white list it) as this is the only source of revenue and it pays for servers,
support and other services. Keep safe in these hard times and help others as
much as you can :).

Update December 2018:
The site is now serving more than 3 million pages per month. Thanks to everyone
for the support and the kind words. I really appreciate it! As usual keep
sending me bug reports if you find issues.

Update September 2016:
I have increased the upload limit to 2 megabytes. Hopefully, the servers will
handle the load. I will evaluate if I can increase it more.

LIST OF TOOLS


JSON FORMATTER / BEAUTIFIER

Formats a JSON string/file with your desired indentation level creating an
object tree with color highlights. You can now clearly identify object
constructs (objects, arrays and members). The JSON tree that is created can be
navigated by collapsing the individual nodes one at a time if desired.

Features
 * Formats your JSON string/file with choice 6 indentation levels: 2 spaces, 3
   spaces, 4 spaces, compact mode, JavaScript escaped and tab separated
 * Creates a tree representation of the JSON objects for easy navigation
 * Color highlights the different construct of your JSON objects
 * Supports copy-paste or file upload


HTML FORMATTER / BEAUTIFIER

Formats a HTML string/file with your desired indentation level. The formatting
rules are not configurable but I think it provides the user with the best
possible output.

Features
 * Formats the HTML with 4 indentation levels: 2 spaces, 3 spaces, 4 spaces and
   tab separated
 * Color highlights the different construct of your HTML document
 * Supports copy-paste or file upload


XML FORMATTER / BEAUTIFIER

Formats a XML string/file with your desired indentation level. The formatting
rules are not configurable but it uses a per-element indentation pattern giving
the best readability.

Features
 * Formats the XML with 4 indentation levels: 2 spaces, 3 paces, 4 spaces and
   tab separated
 * Color highlights the different construct of your XML document
 * Supports copy-paste or file upload


SQL FORMATTER / BEAUTIFIER

Formats any SQL query with your desired indentation level, even if your SQL
statement is invalid. You can modify the case of the SQL keywords and
identifiers to upper case, lower case or keep them as-is.

This SQL beautifier is especially useful for SELECT statements, but can also
handle INSERT, UPDATE and DELETE statements. It was built to be agnostic of the
database that is targeted and should support MySQL, Microsoft SQL Server, Oracle
and other SQL ANSI databases.

Features
 * Formats the SQL with 4 indentation levels: 2 spaces, 3 paces, 4 spaces and
   tab separated
 * Formats the SQL regardless of the validity of the statement
 * Change the case of keywords or identifiers to upper case, lower case or keep
   them as-is
 * Database agnostic
 * Supports SELECT, INSERT, UPDATE and DELETE statements
 * Supports copy-paste or file upload


JSON VALIDATOR

Validates a JSON string against RFC 4627 (The application/json media type for
JavaScript Object Notation) and against the JavaScript language specification.
You can configure the validator to be lenient or strict.

Features
 * Validates your JSON string/file against RFC 4627 in either strict or lenient
   mode
 * Validates your JSON string/file against the JavaScript specification
 * Supports copy-paste or file upload


HTML VALIDATOR

Validates the HTML string/file for well-formedness and compliance with w3c
standards. It tries to make use of the doctype declaration to evaluate the
document structrue but will resort to best practice if unmatched. The validator
will report on missing or invalid attributes, unknown tags, unclosed tags and
more.

Features
 * Validates your HTML string/file using the doctype if possible or the 'best
   practices' if not
 * Checks for invalid tags, missing or invalid attributes, unclosed markeup and
   much more
 * Supports copy-paste or file upload


XML VALIDATOR (XSD)

Validates the XML string/file against the specified XSD string/file. XSD files
are "XML Schemas" that describe the structure of a XML document. The validator
checks for well-formedness first, meaning that your XML file must be parsable
using a DOM/SAX parser. Only then does it validate your XML against the XML
Schema. The validator will report fatal errors, non-fatal errors and warnings.

Features
 * Validates your XML string/file using the provided XSD string/file
 * Supports copy-paste or file upload


XPATH TESTER

Executes an XPath query against an XML file. This online XPath tester will
output the actual matched XML content along with the XML item type (Element,
Text, CData, Attribute, etc.). Each match is displayed on a single line and this
allows you also extract a subset of data if desired. XPath 2.0/3.0 compatible.

Features
 * XPath 2.0/3.0 compatible
 * Supports XML namespaces
 * Extensive support of XPath functions
 * Reports the item type of the matched XML parts
 * Supports copy-paste or file upload


CREDIT CARD NUMBER GENERATOR & VALIDATOR

Validates credit card numbers and also generates fake credit card numbers for
all major brands. Obviously these number are for testing purposes and will not
work with a payment processor. Also contains a full documentation and example of
the Luhn algorithm used to validate most credit cards (Mod 10).

Features
 * Validates credit card numbers
 * List of all card number formats per card issuer
 * Random credit card number generator for all major brands
 * Luhn algorithm explained


REGULAR EXPRESSION TESTER

This regular expression tester will highlight every match in the original string
so that you know exactly where a match occurs. It can be configured to be
case-insensitive, work in multi-line mode and perform global matches. It also
supports string replacements through with groups. It runs against a Java engine.

Features
 * Highlights all matches in the original string
 * Supports the DOTALL flag; i.e. the dot metacharacter matches everything
   including line breaks
 * Supports case-insensitive, multiline and global flags
 * Extensive list of examples and regular expression recipes
 * Supports string replacements


JAVA REGULAR EXPRESSION TESTER

 * Show next run time of cron expression
 * Preview most commonly used cron expression examples


URL ENCODER & DECODER

Encodes or decodes a string so that it conforms to the the Uniform Resource
Locators Specification - URL (RFC 1738).

The specification says that only the following characters are allowed in a URL
"ABCDEFGHIJKLMNOPQRSTUVWXYZabcdefghijklmnopqrstuvwxyz0123456789$-_.+!*'()".
Therefore, all other characters will be encoded to a two digit hexadecimal value
that represents the character in the proper ISO character set.


BASE 64 ENCODER & DECODER

Encodes or decodes a string so that it conforms to the Base64 Data Encodings
specification (RFC 4648).


CONVERT FILE ENCODING

Changes the encoding of a file to another one. For example, this tool will allow
you to change the encoding of your file from ISO-8859-1 to UTF-8 or from UTF-8
to UTF-16.

What encoding is my file using? This tool will try to auto-detect the encoding
used in the file and tell you.


QR CODE GENERATOR

Generates QR codes using various standards such as Address Book / Contact
Information (VCARD), Events (VEVENT), Emails (MAILTO), GEO Coordinates (GEO),
SMS (SMSTO), Telephones (TEL), URLs and WiFi connections. You can also choose
your error correction level from the standards L (Low 7%), M (Medium 15%), Q
(Quartile 25%) and H (High 30%).
