What it does
ParseWiz is a free online tool to convert between JSON, CSV, and Excel files. Unlike other converters, it doesn't just fail on broken files — it shows you exactly where the error is and lets you fix it inline. Upload your file, preview the data in a real table, and download in the format you need. Handles complex nested JSON with smart export options (split tables or flat file). No signup, no data stored.
Free online JSON, CSV, and Excel converter with built-in error fixing. Preview data before download and handle complex nested JSON. No signup required.
Free online converter for your data files. No signup, no upload limits, no data stored. Got a "Parse Error"? No need to open another tool. See exactly where the error is and fix it right here. See your data in a real table with pagination before downloading. No more converting blindly. Nested arrays and objects? Choose between multiple linked tables or a single compact file. Simply drag and drop your JSON file onto the upload area (or click to select it). ParseWiz will automatically detect the format, show you a preview, and let you download as CSV with one click. Unlike other converters that just show "Parse Error", ParseWiz opens an inline editor showing exactly where the error is. Fix it…from parsewiz.app

Talanoa▲346Hi HN, I’m a fullstack developer, and honestly, I’ve lost count of how many side projects I’ve worked on over the years. But one idea kept coming back to me: a different kind of email client. It first came to me in 2014: “What if we could handle emails more like conversations?” Every year, I’d revisit this concept in my “Build Notes.” Ten years later, no one had built exactly what I had in mind — so I finally decided to do it myself.
