SaveCSV2Json is a free tool to convert CSV files to JSON files in a windows GUI. 

JSON is an open-standard format that uses human-readable text to transmit data objects consisting of attribute-value pairs.  It is commonly used for asynchronous browser/server communication, as an alternative to XML.  Read more about JSON formats on Wikipedia. 

A comma-separated values (CSV) file stores tabular data (numbers and text) in plain text.  Each line of the file is a separate data record.  And each record consists of one or more fields, separated by commas.  Read more about CSV formats on Wikipedia. 

The CSV file format is not standardised, however we assume the common formatting used by most spreadsheet programs, such as Microsoft Excel or OpenOffice Calc.  Text fields may include commas and other formatting, such as line-breaks, provided the text field is surrounded by quotation marks ("...").  If text fields need to include quotation marks, they must be doubled.  For example (He said "hello".) must become ("He said ""hello"".") in a CSV file, to be properly read by a spreadsheet program. 

SaveCSV2Json will create a separate key in the JSON file for each column in the CSV file.  The first line in a CSV file may be a list of the column headers.  SaveCSV2Json provides a checkbox where the user may indicate whether to use the first line of each CSV file as a list of headers. 

The user may also decide whether to make the CSV data as a simple array in JSON format, or whether to name the array element.
