Free tools from ReactBD

A JSON workspace that runs in the browser. Format and pretty-print payloads, validate syntax, minify for size, compare two objects, convert arrays to CSV, and generate mock users or products. Copy or download the result without sending data to a server.

A cleaner for text that arrived with extra line breaks. Paste copy from a PDF, email, or code dump and get a single continuous block back. Use it when OCR, chat exports, or PDFs wrap lines you need as one string for editing or paste.

A browser converter for everyday image formats. Turn JPG, PNG, WebP, and related files into the format your site or CMS expects, then download the result. Use it to match a pipeline, shrink an asset, or prepare images before they go live.

A generator for secure random tokens used in auth, APIs, and tests. Create API keys, secrets, and session-style strings at the length you need, then copy them into env files or fixtures. You get usable secrets without writing a script.

A checker for Node.js package.json dependencies. Load a manifest, see which packages are behind, and bump versions in one pass. You get an updated package.json to commit and install, so the app stays on current, compatible releases.

A free mock REST API of e-commerce JSON — users, products, carts, orders, and reviews. Call the endpoints from a storefront, tutorial, or prototype without standing up a backend. The records are structured so UI work can start immediately.
