Up to 5 MB / 100,000 output rows. Exact strings preserved, including empty values. This changes table structure only; it does not establish statistical independence. Spreadsheet formula-like values are preserved: import untrusted text as text.
Inputs stay in your browser. No account or data upload. Hosting may retain ordinary access logs.
