The tool provides detailed error feedback including line and column information, and processes all data locally without server dependency. The developer chose to solve a recurring developer problem rather than chase the AI trend, aiming for long-term utility over short-term hype.", "body_md": "Everyone seems to be building AI products right now.\n\nOpen LinkedIn, Product Hunt, or Twitter, and you'll find hundreds of new AI tools launching every week. Most of them are built on top of existing AI models and compete in an increasingly crowded market.\n\nWhen I started looking for my next side project, I asked myself a simple question:\n\nShould I build another AI app, or should I solve a real problem that developers face every day?\n\nI chose the second option.\n\nThat's how Online JSON Tools was born.\n\nAs a backend developer, I work with JSON constantly. API requests, API responses, configuration files, third-party integrations, log files, and microservices all rely heavily on JSON. On some days, I spend more time reading JSON than writing actual business logic.\n\nDespite that, many online JSON tools felt outdated, cluttered, or incomplete.\n\nSome had intrusive ads everywhere.\n\nSome had poor dark mode support.\n\nSome simply showed \"Invalid JSON\" without explaining what was actually wrong.\n\nOthers struggled with larger files or provided a poor editing experience.\n\nI wanted something better.\n\nSo instead of building another AI wrapper, I decided to build a tool that developers could genuinely use every day.\n\nThe Goal\n\nThe goal was simple:\n\nCreate a fast, developer-focused JSON utility platform that prioritizes usability, performance, and clarity.\n\nNo unnecessary features.\n\nNo complicated setup.\n\nNo server dependency for basic operations.\n\nJust a tool that helps developers work with JSON faster.\n\nWhat the Tool Does\n\nCurrently, Online JSON Tools focuses on the most common JSON workflows:\n\nBeautifying JSON\n\nMinifying JSON\n\nValidating JSON\n\nIdentifying syntax errors\n\nShowing line and column information\n\nCopying formatted output\n\nDownloading processed JSON\n\nSupporting dark mode for long development sessions\n\nEverything happens directly in the browser.\n\nYour JSON never needs to leave your machine for basic formatting and validation tasks.\n\nOne Problem I Wanted to Fix\n\nMost validators stop at:\n\nInvalid JSON\n\nThat message is technically correct.\n\nBut it doesn't help much.\n\nImagine opening a 500-line JSON document and being told only that it's invalid.\n\nNow you have to search through the entire file trying to locate the issue yourself.\n\nInstead, I wanted the validator to provide useful feedback:\n\nWhich line contains the error\n\nWhich column contains the error\n\nWhat caused the problem\n\nA suggested fix\n\nSomething as simple as a trailing comma can waste several minutes when you're dealing with large payloads.\n\nGood tooling should reduce that friction.\n\nWhy Not Build an AI Product?\n\nThis was probably the biggest decision.\n\nAI products are attractive because they are trending.\n\nBut trends change quickly.\n\nUtility tools solve recurring problems.\n\nDevelopers were formatting JSON ten years ago.\n\nDevelopers are formatting JSON today.\n\nDevelopers will probably still be formatting JSON ten years from now.\n\nThat makes the problem far more stable than chasing whatever technology trend happens to be popular this month.\n\nI wanted to build something with long-term value rather than short-term hype.\n\nTechnical Decisions\n\nI kept the initial architecture intentionally simple.\n\nThe platform is built using:\n\nNext.js\n\nTypeScript\n\nTailwind CSS\n\nMonaco Editor\n\nThe first version is frontend-only.\n\nThat decision offers several advantages:\n\nFaster deployment\n\nLower hosting costs\n\nBetter performance\n\nEasier maintenance\n\nNo backend infrastructure\n\nSince formatting and validation can happen entirely in the browser, there was no reason to introduce unnecessary complexity.\n\nSometimes the best architecture is the simplest one that solves the problem effectively.\n\nChallenges During Development\n\nWhat looked like a simple weekend project quickly became more complicated.\n\nA JSON formatter sounds easy.\n\nPaste JSON.\n\nCall JSON.parse().\n\nDisplay the result.\n\nDone.\n\nReality was different.\n\nI spent significant time improving the editing experience, handling validation errors properly, refining the interface, and making sure the tool behaved the way developers expect.\n\nOne of the most interesting challenges was making validation feedback useful instead of generic.\n\nAnother was ensuring the editor experience felt smooth and professional.\n\nThe goal wasn't just functionality.\n\nThe goal was usability.\n\nWhat I Learned\n\nBuilding developer tools taught me something important:\n\nYou don't need a revolutionary idea to create a useful product.\n\nYou don't need AI.\n\nYou don't need blockchain.\n\nYou don't need a complex SaaS platform.\n\nSometimes solving a small, annoying problem well is enough.\n\nDevelopers appreciate tools that save time.\n\nEven if that time savings is only a few minutes per day.\n\nThose minutes add up.\n\nWhat's Next?\n\nOnline JSON Tools is still growing.\n\nFuture improvements include:\n\nJSON Diff Tool\n\nJSON Tree Viewer\n\nJSON Repair\n\nJSON Escape and Unescape\n\nAdditional developer utilities\n\nThe vision is to create a practical toolkit that developers can rely on whenever they need to inspect, validate, transform, or analyze JSON.\n\nFinal Thoughts\n\nBuilding another AI application would have been the obvious choice.\n\nBuilding a JSON utility platform was the less exciting option.\n\nBut it was also the more practical one.\n\nI developed Online JSON Tools because I wanted a faster and more developer-friendly way to work with JSON. Sometimes the best projects aren't the ones that follow the latest trend. They're the ones that solve a problem people already have.\n\nIf you're a developer, what JSON-related task do you find yourself doing most often?", "url": "https://wpnews.pro/news/why-i-built-online-json-tools-instead-of-another-ai-app", "canonical_source": "https://dev.to/kalaivani_r_c92f3dfc4220c/why-i-built-online-json-tools-instead-of-another-ai-app-1dda", "published_at": "2026-06-11 20:32:22+00:00", "updated_at": "2026-06-11 20:41:40.885610+00:00", "lang": "en", "topics": ["ai-tools", "ai-products", "ai-startups"], "entities": ["Online JSON Tools", "LinkedIn", "Product Hunt", "Twitter"], "alternates": {"html": "https://wpnews.pro/news/why-i-built-online-json-tools-instead-of-another-ai-app", "markdown": "https://wpnews.pro/news/why-i-built-online-json-tools-instead-of-another-ai-app.md", "text": "https://wpnews.pro/news/why-i-built-online-json-tools-instead-of-another-ai-app.txt", "jsonld": "https://wpnews.pro/news/why-i-built-online-json-tools-instead-of-another-ai-app.jsonld"}}
