Engineers Behind It All

Two Laptops, Late Nights, and a 2016 College Project

It all started back in 2014 over lines of code and shared dreams during our Bachelor of Computer Application days. We were Kartik and Bhavya - a classic college team always building something, whether it was for a class assignment or a late-night side project. We had big ambitions to build things that mattered, but life took its usual twists.

I chased a dream of joining the Indian Armed Forces, reaching the final SSB rounds multiple times, before we both eventually landed at TCS. Corporate routines set in, life got busy, and in 2024, we officially tied the knot.

Then came a pivotal late-night working session. Sitting side-by-side with our laptops open, we found ourselves reflecting on where that original spark went. 'Remember how ambitious we were in college?' turned into a challenge - why not actually put something live? We decided to take baby steps and revive an old data formatting and parsing tool we had originally hacked together as a college project back in 2016. No corporate pressure, no intense competitive strategy - just two engineers trying to reconnect with the fun of building software for real end-users.

That spontaneous spark became Online JSON Formatt - or as we like to call it, Only Jokes Forever (OJF). What started as an inside joke and a wave of nostalgia quickly turned into a dedicated, clean, and reliable utility designed to solve the everyday data formatting headaches we both faced in our corporate engineering jobs.

Today, we run this platform together as an engineering couple - constantly tweaking, optimizing, and ensuring you get a fast, bloat-free experience every time you need to clean up messy JSON.
