@David I’m afraid converting JSON to CSV is not really possible because JSON is a much more expressive data format than CSV. This means only a very small proportion of JSON files could meaningfully be translated into CSV.

I would like to convert a .json fle to a .csv file, and in googling for something I found your http://tamlyn.org/2009/06/csv2json-convert-csv-to-json/ about converting .csv to .json.

Do you have a way of converting a .json fle to a .csv file? Certainly would ‘preciate it!

Good job Tamlyn!

I needed to convert csv files from command-line.
Here is a small ruby project nicely packaged as a ruby gem:

@zeynel It has to be a plain text CSV file. It won’t work in Google Docs because that creates an HTML file.

Hello,

I tried this but it didn’t work. I put the csv file in google docs and published it and i put in the url to convert but did not work. Any idea why?

Sure thing. Here's the important bit:

$fp = @fopen($_GET['csv'], 'r');

$headers = fgetcsv($fp, 2048);

$data = array();
while ($row = fgetcsv($fp, 2048)) {
	$item = array();
	foreach ($row as $key => $cell) {
		$item[$headers[$key]] = utf8_encode($cell);
	}
	$data[] = $item;
}

header('Content-type: text/javascript');
echo json_encode($data);

Great work!

I was wondering wether you’d let me take a look at the source code, so I can implement it using ActionScript. I have some CSV files I need to convert to JSON. This of course, is part of a bigger project, but unfortunately time is something I lack right now. I’d appreciate it if you could lend me a hand.

Anyway, I know this is a long shot. I understand if you prefer to do otherwise.

Thanks!
