I am trying to read a text file using node js fs module. My first question is , Does fs module support to read only text file or other file formats too ?
Now My main question is if the text file have the data like below, How do i read each data separately in the file ?..Please note some cell in the row could be empty as well.

The fs
module doesn't understand file formats, it just reads buffers. Optionally it can convert the buffers into strings. As for that file, it's a csv just with |
instead of ,
.
Parsing it is somethings like:
// split the lines into rows
const rows = raw.split('\n');
// split into collumns
const data = rows.map(row => row.split('|'));
The empties will just be empty strings in the row arrays. You can filter them out. rows.map(row => row.split('|').filter(el => el !== ''))
but most likely you'll want to leave them in for easy access my index.
But that assumes there are no escapes or other irregularities. I recommend finding a csv module from npm.
