Saving an array to a text file with a new line delimiter can easily be achieved using Types

I have an array of plain strings that I need to save to a text file. However, I'm encountering an issue where the strings are being saved as comma separated values instead of new lines.

Here is the data I currently have: https://i.sstatic.net/r3XVr.jpg

And here is the file I'm currently getting: https://i.sstatic.net/obKXf.jpg I am creating the file using the following code snippet:

let newFile = new Blob([result['list']], {type: "text/plain", endings: 'native'});

The 'result' variable is fetched from the server. Is there a way to ensure that each element in the array appears on a new line in the text file generated using File/Blob, or is there a different approach I should consider?

Answer №1

One issue arises when the array [1,2,3] gets converted into a string "1,2,3". You can verify this by executing String([1,2,3]) in your browser console.

To work around this problem, consider trying:

let newFile = new Blob([result['list'].join('\n')], {type: "text/plain", endings: 'native'});
