How to replace imports with code in Scss file?

Question

css

It is necessary to make another scss file from one scss file, in which there are a lot of imports, in which all imports are replaced by the code that they include.
I am importing whole scss files, I need to make a new file with pure code, no imports. Maybe some gulp plugin?

Export file:

@mixin font-h1 {
  color: #333;
  font-size: 60px;
  font-weight: 600;
  line-height: 1.4;
}

Import file

h1 {
  @include font-h1;
}
