What is CSV to JSON Converter?

Spreadsheets and data exports from Excel, Google Sheets, or database reports are formatted in CSV, while web developers require JSON for web applications. This tool allows instant transformation of raw tabular CSV data into clean JSON objects or flattening of JSON arrays into CSV files.
