Introduction
As developers, we work with data every single day.
Whether it’s JSON responses from APIs, CSV exports from databases, JWT tokens, timestamps, or SQL queries — small formatting and conversion tasks are part of our routine.
To make these tasks easier and faster, I built a simple Developer Tools platform that includes the most commonly used utilities in one place.
In this article, I’ll briefly explain each tool and how it can help simplify your workflow.
JSON Viewer
Large JSON files can be difficult to read and may even freeze the browser when improperly formatted.
The JSON Viewer helps you:
View and format large JSON files
Expand and collapse nested objects
Read deeply structured data more easily
Detect invalid JSON instantly
It is designed to handle large JSON more efficiently and keep the interface responsive.
If you work with API responses, logs, or webhook payloads, this tool can save you a lot of time.
JSON to CSV Converter
APIs usually return data in JSON format, but many business tools and spreadsheets require CSV.
The JSON to CSV Converter allows you to:
Convert structured JSON data into CSV format
Quickly export API responses to Excel
Transform data for reporting
Just paste your JSON and get a properly formatted CSV output instantly.
This is especially useful when working with reporting tools or sharing structured data with non-technical teams.
CSV to JSON Converter
If you have CSV data from Excel or a database export and need to use it in an application, converting it to JSON becomes necessary.
The CSV to JSON Converter helps you:
It removes the need for manual conversion.
XML Formatter
XML can be hard to read when compressed into a single line.
The XML Formatter:
It is especially helpful when debugging integrations or configuration files.
Base64 Encoder & Decoder
Base64 encoding is commonly used in:
Authentication headers
Tokens
Data transfer
Emails
The Base64 Encoder/Decoder allows you to:
A simple tool, but very useful during debugging.
Timestamp Converter
Unix timestamps are common in logs and APIs, but not easy to read directly.
The Timestamp Converter lets you:
Convert Unix timestamps into human-readable dates
Convert readable dates back into timestamps
Understand time-based data quickly
This is particularly useful when analysing logs or troubleshooting time-related issues.
JWT Decoder
JWT (JSON Web Token) is widely used for authentication.
The JWT Decoder allows you to:
It helps you debug authentication flows easily.
SQL Formatter
Unformatted SQL queries can be difficult to read and maintain.
The SQL Formatter:
Especially helpful for complex joins and nested queries.
Privacy & Security
One important aspect of these tools is privacy.
All processing happens directly in the browser:
This ensures a secure and safe experience, even when working with sensitive data.
Why These Tools Matter
Small repetitive tasks can slow down development.
Instead of switching between multiple websites or writing small scripts repeatedly, having essential developer tools in one place improves productivity and efficiency.
The goal of this platform is simple:
Fast
Lightweight
Secure
Easy to use
More tools and improvements will continue to be added.
Final Thoughts
If you regularly work with JSON, CSV, XML, SQL, JWT tokens, or timestamps, having quick and reliable utilities can make your daily workflow smoother.
I’d love to hear which tool you find most useful and what additional features would help you the most.
Summary
This Developer Tools platform brings together commonly used utilities such as JSON viewers, format converters, SQL formatting, JWT decoding, and timestamp conversion into one lightweight and secure interface. By handling all processing locally in the browser, it ensures privacy while helping developers save time on everyday formatting and debugging tasks.
