Agree — and a practical chunk of "personal data storage" is just not uploading raw exports to random SaaS cleaners.

I keep a tiny local tool for that: CleanCSV. Drop/paste a CSV or TSV (8 MB cap); profiling and cleaning run 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.
