About CSV and delimiters
CSV (comma-separated values) is the lowest-common-denominator data format, but the separator varies: spreadsheets in some locales use a semicolon, exports often use tabs (TSV) or pipes. This viewer scans the first row, picks the most likely delimiter, and respects quoted fields ("value, with comma") and escaped quotes ("").
Privacy
The file you drop is read with the browser's FileReader API and parsed in memory. No request is made, nothing is uploaded. Open DevTools → Network and watch: the tab stays silent.
