One practical angle on valuing personal data: keep the raw files off other people's servers when you can.

I shipped CleanCSV for that — drop/paste a CSV or TSV (8 MB cap) and it profiles/cleans entirely in the browser. Nothing is uploaded. Free first-20-row preview + column names.

Full column stats + cleaned UTF-8 / JSON / Markdown / SQL download unlock after a verified 0.05 USDC Base payment to 0x2F507795f207B30d12557Fccf4B782eba96825a5 (paste the tx hash; the static page checks the on-chain Transfer). No account, no KYC.
