tsv-parser
tsv-parser
can convert TSV into JSON
Install
$ npm install @smnblmrr/tsv-parser
Example
Begin by setting up a readable stream to the TSV file you intend to parse. Once done, initiate TsvParser
and direct the stream to flow through it.
Imagine you're working with a TSV file named data.tsv
. The content might look something like this:
NAME AGE
Daffy Duck 24
Bugs Bunny 22
Here's how you'd extract and display the information using TsvParser:
const { createReadStream } = require("node:fs");
const TsvParser = require("@smnblmrr/tsv-parser");
let source = createReadStream("data.tsv");
let data = [];
source
.pipe(TsvParser())
.on("data", (record) => {
data.push(record);
})
.on("end", () => {
console.log(data);
});
When you run the above script, you can expect an output resembling:
[
{ NAME: 'Daffy Duck', AGE: '24' }
{ NAME: 'Bugs Bunny', AGE: '22' }
]
Options
Type: Object
headers
Type: Array[String] | Boolean
The headers option determines how the TSV rows are mapped to object properties. If you don't provide a specific headers option, the tsv-parser assumes that the first row in your TSV file contains the headers.
By setting the headers option to false, you're telling the parser that the first row doesn't contain headers. Instead, the parser will use the column indices as keys.
