You can choose between strict string parsing (preserving all cell contents as string literals) or auto-type inference, which automatically detects numbers, booleans (true/false), and null values.

Frequently Asked Questions about CSV to JSON Converter
Quick answers to common questions about usage, conversion rules, privacy guarantees, and best practices.
How does CSV to JSON conversion parse data types?
Can this tool parse CSV files with custom delimiters like semicolons or tabs?
Yes. The converter supports auto-detection of delimiters as well as manual selection of commas, semicolons (;), tabs (TSV), and pipe characters (|).
How does the tool handle missing values or empty cells in CSV rows?
Empty cells can be preserved as empty string literals (""), omitted from the generated object, or mapped to null values based on your parsing preferences.
