How to work with a large array of geopoints?

Question

Design

There are many boundaries of rural settlements in geocoordinates for Yandex.Maps:

[60.432650, 46.376516],
[60.430968, 46.379661],
[60.427759, 46.385709],
[60.425611, 46.388227],
[60.422302, 46.394414],
[60.419057, 46.400400],
[60.416291, 46.405504]
...

It is necessary to change these boundaries in a certain way, but hitting the desired area by typing is a chore, because hundreds of thousands of points.
In what graphical editor can such an array of data be inserted, edited, and the array returned?

Answer 1

I came up with the idea to overtake the coordinates in SVG format, and edit there, then convert back

Answer 2

Try the OpenStreetMap editor, there you can import/export geocoordinates to vector data. Whether it will give points in this format, I'm not sure.
