Under the Hood: Reliable CSV Parsing

Automatic Delimiter Detection

Our parser analyzes frequency distributions of candidate characters across the header lines, reliably detecting whether the file uses commas, semicolons, tabs, or pipe symbols.

Intelligent Type Coercion

Strings like "42.5" and "true" are cast into native JSON numbers and booleans, while strings with leading zeros (e.g. zip codes "07030") are preserved safely.

Multiline Quoted Cells

Supports standard RFC 4180 multiline cells containing embedded newlines and quotes without accidentally splitting records across broken rows.
