Frequently Asked Questions

What CSV features are supported?

This tool uses PapaParse, which handles quoted fields, escaped quotes, various delimiters (comma, semicolon, tab, pipe), optional headers, and automatic type detection (numbers, booleans). It correctly handles multi-line quoted fields.

How do I handle CSV with special characters?

PapaParse automatically handles values containing commas or newlines when they're wrapped in double quotes. If your CSV uses a different delimiter (e.g., semicolons in European locales), change the delimiter setting.
