OK so data formats are weirdly annoying. Your coding project needs JSON but all your data is sitting in an Excel file (CSV). Or an API gave you this giant JSON blob and you need to open it in Excel to actually see what's in it. Manually copy-pasting is torture and you WILL miss stuff or mess up the formatting. CSV-to-JSON is probably our most-used data tool - takes a spreadsheet export and converts it straight to clean JSON that your code can actually use. It even figures out automatically if you used commas, tabs, or semicolons to separate things (because apparently everyone does it differently). JSON-to-CSV does the opposite - flattens all that nested data into nice spreadsheet rows so you can open API responses in Excel or Google Sheets like a normal person. JSON Formatter is for when you copy some JSON from a debug console and it's all on one line and completely unreadable. Makes it pretty with proper indentation and colors, plus checks if you forgot a comma or quote somewhere. There's also XML converters which... honestly I don't use XML much anymore but apparently enterprise software still does, so we have tools for that too. The important thing: everything happens in your browser. If you're converting customer databases or anything with emails or personal info, it never leaves your computer. Never goes to a server. This is kind of a big deal for GDPR and privacy laws and just not getting in trouble for leaking data. Also means it's instant even on huge files because there's no upload/download wait. Really useful whether you're learning to code and need to wrangle data for a project, or working with APIs, or just trying to make sense of some export file your boss sent you.
