Why use PDFPremium.pro?
Excel speaks CSV, every API speaks JSON, and someone always has to translate. Paste CSV with a header row and get a clean JSON array; paste a JSON array and get proper CSV with correct quoting - including the tricky cases like commas inside values and quotes inside quotes that break amateur converters. Data stays in your browser, which matters when the file is a customer list. As with every tool here, it runs entirely inside your browser - no uploads, no sign-ups, no watermarks.
Frequently asked questions
Does it handle commas inside values?

Yes — completely free with no hidden limits, watermarks, or sign-up. The site is supported by light advertising.
Are my files uploaded to a server?
No. Everything runs inside your browser using JavaScript — your files never leave your device, ever.
