How to quickly format a file?

Question

Text Processing Automation

I have a txt file like this:

spoiler

----Slovo1-------slovo2------12Slovo----------34452gSlovo
----Slovo345-----Slovo234--slovo234----- --Slovo6643
and more than 1000 such lines
' - ' is a space

You need to format it so that all the first spaces (before the characters) are removed, and the rest become |. It should turn out something like:

file.txt

Slovo1|slovo2|12Slovo|34452gSlovo
Slovo345|Slovo234|slovo234|Slovo6643
and more than 1000 such lines

Answer 1

In any text editor that supports regular expression search/replace
Replace ^\s+ with nothing
Replace \s+ with |

Answer 2

For example like this:

let text = `
    Slovo1      slovo2        12Slovo        34452gSlovo
    Slovo345     Slovo234  slovo234      Slovo6643
`;

console.log(text);
text = text.replace(/\s\s+/g, '|');
console.log(text);

Or take a regular expression from there and apply it in other ways :)
