converting CSV/XLS to JSON? [closed]

Question

Does anyone know if there is application that will let me convert preferably XLS to JSON?

I'll also settle for a converter from CSV since that's what I'll probably end up having to write myself if there is nothing around.

Answer 1

You can try this tool I made:

Mr. Data Converter

It converts to JSON, XML and others.

It's all client side, too, so your data never leaves your computer.

Answer 2

If you can't find an existing solution it's pretty easy to build a basic one in Java. I just wrote one for a client and it took only a couple hours including researching tools.

Apache POI will read the Excel binary. http://poi.apache.org/

JSONObject will build the JSON

After that it's just a matter of iterating through the rows in the Excel data and building a JSON structure. Here's some pseudo code for the basic usage.

FileInputStream inp = new FileInputStream( file );
Workbook workbook = WorkbookFactory.create( inp );

// Get the first Sheet.
Sheet sheet = workbook.getSheetAt( 0 );

    // Start constructing JSON.
    JSONObject json = new JSONObject();

    // Iterate through the rows.
    JSONArray rows = new JSONArray();
    for ( Iterator<Row> rowsIT = sheet.rowIterator(); rowsIT.hasNext(); )
    {
        Row row = rowsIT.next();
        JSONObject jRow = new JSONObject();

        // Iterate through the cells.
        JSONArray cells = new JSONArray();
        for ( Iterator<Cell> cellsIT = row.cellIterator(); cellsIT.hasNext(); )
        {
            Cell cell = cellsIT.next();
            cells.put( cell.getStringCellValue() );
        }
        jRow.put( "cell", cells );
        rows.put( jRow );
    }

    // Create the JSON.
    json.put( "rows", rows );

// Get the JSON text.
return json.toString();

Answer 3

None of the existing solutions worked, so I quickly hacked together a script that would do the job. Also converts empty strings into nulls and and separates the header row for JSON. May need to be tuned depending on the CSV dialect and charset you have.

#!/usr/bin/python
import csv, json
csvreader = csv.reader(open('data.csv', 'rb'), delimiter='\t', quotechar='"')
data = []
for row in csvreader:
    r = []
    for field in row:
        if field == '': field = None
        else: field = unicode(field, 'ISO-8859-1')
        r.append(field)
    data.append(r)
jsonStruct = {
    'header': data[0],
    'data': data[1:]
}
open('data.json', 'wb').write(json.dumps(jsonStruct))

Answer 4

This worked perfectly for me and does NOT require a file upload:

Answer 5

I just found this:

http://tamlyn.org/tools/csv2json/

( Note: you have to have your csv file available via a web address )

Answer 6

Take a try on the tiny free tool:

http://keyangxiang.com/csvtojson/

It utilises node.js csvtojson module
