如何使用JavaScript将对象转换为CSV？

Question

我想将此对象转换为CSV文件.列名应该是键,这是一小块数组.并且最后一个数组将只是一种(键),所有其他数组将具有相同的键但不同的值.

Answer 1

这是一个简单的实现:

// Returns a csv from an array of objects with
// values separated by tabs and rows separated by newlines
function CSV(array) {
    // Use first element to choose the keys and the order
    var keys = Object.keys(array[0]);

    // Build header
    var result = keys.join("\t") + "\n";

    // Add the rows
    array.forEach(function(obj){
        result += keys.map(k => obj[k]).join("\t") + "\n";
    });

    return result;
}
