How could I convert all column names in a dataframe to snake_case?

[Ilya Muradyan]

If you have your function toSnakeCase() that converts any String to snake case, then it can be done this way:

df.rename { all() }.into { it.name.toSnakeCase() }

Thanks @Ilya Muradyan. the snake case part is easy -> https://stackoverflow.com/questions/60010298/how-can-i-convert-a-camel-case-string-to-snake-case-and-back-in-idiomatic-kotlin

Yes, it's easy but it depends on your particular case - you may initially have CamelCase, space separated words or anything else)
