Free Online Developer Tools for Coding, Formatting and Data Conversion
Software development frequently involves small but repetitive tasks: checking JSON syntax, formatting HTML, encoding a URL parameter or converting a timestamp into a readable date.
ToolDest brings together online developer utilities that help with these everyday operations.
These tools can be useful for software developers, web designers, technical students, testers and people working with APIs or structured data.
Format and Check JSON
JSON is widely used to exchange structured data between applications and services.
A JSON formatter can make nested objects and arrays easier to read. It may also help identify syntax problems, such as missing commas or unmatched brackets.
Formatting JSON does not guarantee that the data matches a particular API’s required schema.
Explore the JSON Formatter.
Encode and Decode Base64
Base64 represents binary or text data using a set of printable characters.
It appears in data transmission, development workflows and some API integrations.
Base64 is not encryption. Anyone with access to encoded data can generally decode it, so it must not be used as a security measure for confidential information.
Explore the Base64 Encoder/Decoder.
Format HTML
Readable HTML is easier to inspect and maintain.
An HTML formatter can help organise markup and indentation, particularly when working with code that has been copied from another source.
However, formatting alone does not establish that HTML is accessible, semantically correct or secure.
Explore the HTML Formatter.
Encode URLs Correctly
URLs can contain characters that need special handling when used as parameters.
For example, spaces and reserved characters may need encoding to preserve the intended meaning of a query value.
It is important to distinguish encoding a parameter value from encoding an entire URL.
Explore the URL Encoder/Decoder.
Generate UUIDs
Universally Unique Identifiers are commonly used as identifiers in software systems.
They can be useful when creating test records, working with distributed applications or generating identifiers that do not depend on a simple sequential number.
A UUID is not automatically a secret token and should not be treated as a substitute for secure authentication credentials.
Explore the UUID Generator.
Convert Unix Timestamps
Unix timestamps represent time relative to a defined epoch.
Developers may encounter them in logs, APIs, databases and event records.
A timestamp converter can make numeric values easier to interpret. Always check whether the source uses seconds or milliseconds and which time zone is intended.

Frequently Asked Questions
Does a JSON formatter fix every JSON error?
No. A formatter may help identify invalid syntax, but it cannot determine the intended meaning of missing or incorrect data.
Is Base64 suitable for passwords?
No. Passwords require appropriate secure storage and hashing practices, not reversible Base64 encoding.
Are UUIDs guaranteed to be unique?
UUIDs are designed to make collisions extremely unlikely when generated correctly, but absolute uniqueness cannot be guaranteed in every circumstance.
Why is my converted timestamp showing the wrong date?
Check whether the input uses seconds or milliseconds and whether the displayed date is in UTC or a local time zone.
Simplify Your Development Workflow
Use ToolDest’s developer utilities to inspect, format and convert supported data. Avoid entering production credentials, private keys or confidential records into online tools without first verifying their data-processing arrangements.
