When You Need CSV to JSON Conversion
APIs expect JSON. Databases accept JSON imports. Node.js scripts, Python data pipelines, and React components all prefer JSON over CSV. Converting CSV to JSON is a daily task for developers, data analysts, and backend engineers. FreeFileKit's converter handles header rows, quoted fields, and escaped commas correctly.
Conversion Options
Array of objects (default): each row becomes a JSON object keyed by column headers — the most common format for APIs. Array of arrays: raw 2D array, suitable for data processing scripts. Keyed object: specify a column as the primary key — each row becomes a property on the root object. This is ideal for lookup tables.
Handling Edge Cases
Quoted fields: values like 'Smith, John' (with a comma inside quotes) are handled correctly. Unicode: all UTF-8 characters pass through without escaping. Empty cells: converted to null or empty string depending on the option you select. Numeric coercion: optionally convert numeric-looking strings to actual numbers.
