🧾 CONVERTER SUITE • 100% PRIVATE
Free Converters Online — CSV, JSON, Base64, Epoch, Cases & QR
Data in one shape, out in the other — CSV/JSON, Base64, epoch, cases, slugs, QR and URL encoding, all computed locally.
Converters are the glue between tools: the spreadsheet is CSV, the API is JSON, the API key is Base64, the log line is an epoch, the variable list needs a case rename, the URL is a slug. Our converter suite handles the conversions developers and data people run weekly, with proper handling of the edge cases — quoted CSV fields containing commas, Unicode in slugs, and URL query strings that bite you when encoded twice. Because everything is local, a database export with real customer data can be converted without ever touching a stranger’s server.
FAQ
- Can the CSV converter handle quoted fields with commas inside? Yes — standard CSV quoting (double quotes around fields, doubled quotes inside) is parsed and generated correctly in both directions.
- Is Base64 encode/decode secure for API keys? Yes — and it is safer than a random online converter precisely because the key never leaves your browser. Nothing is logged, uploaded, or stored.
