The csv to json works like this: it parses CSV (quoted fields, embedded commas, CRLF) into JSON arrays with auto-typed numbers and booleans. Everything happens on your device - the input never leaves your tab unless the tool clearly states it performs a server-side lookup.

Frequently asked questions
Can it keep everything as strings?
Yes - disable auto-typing to preserve leading zeros in IDs and postal codes.
Are quoted fields with embedded commas parsed correctly?
Yes - RFC-4180 quoting is respected, so "Last, First" stays one field and embedded newlines inside quotes survive too.
When do numbers and booleans get auto-typed?
When a column's values all look like numbers or true/false they convert to JSON numbers and booleans; anything ambiguous stays a string, which is the safe default.
