How to convert values from certain keys of an array to numbers?

I have the following array of objects

const mi_array = [{
  agrupacion: "Total país",
  col2015: '81.8',
  col2016: '86.4',
  col2017: '67.3',
  col2018: '70.8',
  col2019: '67.6'
},{
  agrupacion: "otra cosa",
  col2015: '90.8',
  col2016: '67.4',
  col2017: '39.3',
  col2018: '50.8',
  col2019: '95.6'
}];

I need to transform this into something like this:

const new_array = [{
  name: "Total país",
  data: [81.8, 86.4, 67.3, 70.8, 67.6]
}, {
  name: "otra cosa",
  data: [90.8, 67.4, 39.3, 50.8, 95.6]
}];

I tried this but since values on keys col2015 thru 2019 are all strings, it doesn’t work as intended

const result = mi_array.map(e => ({
  name: e.agrupacion,
  data: Object.values(e).filter(e => typeof e == 'number')
}))

console.log(result)

output:

[{
  data: [],
  name: "Total país"
}, {
  data: [],
  name: "otra cosa"
}]

I know it will work if I can transform those values into numbers somehow so i tried to achieve that with this:

for(let key of Object.keys(mi_array))  mi_array[key] = +mi_array[key]

console.log(mi_array);

however my output is:

[NaN, NaN]

another attempt:

var result = Object.keys(mi_array).map(function(key) {
  return [Number(key), mi_array[key]];
}); 

console.log(result); 

another failed output:

[[0, {
  agrupacion: "Total país",
  col2015: "81.8",
  col2016: "86.4",
  col2017: "67.3",
  col2018: "70.8",
  col2019: "67.6"
}], [1, {
  agrupacion: "otra cosa",
  col2015: "90.8",
  col2016: "67.4",
  col2017: "39.3",
  col2018: "50.8",
  col2019: "95.6"
}]]

Is there an efficient way of doing this?

>Solution :

You could destructure name and take from the rest only the values as data, after mapping with Number.

This approach takes the original order of the object.

const
    mi_array = [{ agrupacion: "Total país", col2015: '81.8', col2016: '86.4', col2017: '67.3', col2018: '70.8', col2019: '67.6' }, { agrupacion: "otra cosa", col2015: '90.8', col2016: '67.4', col2017: '39.3', col2018: '50.8', col2019: '95.6' }],
    result = mi_array.map(({ agrupacion: name, ...o }) => ({
        name,
        data: Object.values(o).map(Number)
    }));

console.log(result);
