Every CSV converter online makes you upload your file to a server. Fine for a grocery list, less fine for a customer export. The CSV Pro runs entirely in your browser. Nothing is uploaded, nothing is stored. 20 tools: CSV to JSON, Excel, SQL, XML, Markdown. Excel to CSV, JSON, SQL, HTML. Plus a viewer with search and sort, split, merge, dedupe and a delimiter converter. No account, no limits, no watermark.

I kept running into the same thing. I needed a CSV turned into JSON, or a file split, and every tool online wanted me to upload it first. Half of those files had customer data in them. So I built the version that doesn't. Everything parses in your browser. No backend, no upload, no account. Open devtools and watch the network tab stay empty. It started as one converter and turned into 20, all sharing one RFC 4180 parser, because the edge cases are where these tools usually break. Quoted commas, embedded newlines, BOM, semicolon delimiters from European Excel. Free, no signup. If a format you need is missing, tell me and I'll add it.
