Detects and removes thousand separators (dot/comma/quote/space) from string-type digits
## Install
This package is [pure ESM](https://gist.github.com/sindresorhus/a39789f98801d908bbc7ff3ecc99d99c). If you're not ready yet, install an older version of this program, 5.1.0 (`npm i string-remove-thousand-separators@5.1.0`).
```bash
npm i string-remove-thousand-separators
```
## Quick Take
```js
import { strict as assert } from "assert";
import { remSep } from "string-remove-thousand-separators";
// π¬π§ πΊπΈ thousand separators:
assert.equal(remSep("1,000,000.00"), "1000000.00");
// π·πΊ thousand separators:
assert.equal(remSep("1 000 000,00"), "1000000,00");
// (if you want it converted to Western notation with dot,
// set opts.forceUKStyle = true
// π¨π thousand separators:
assert.equal(remSep("1'000'000.00"), "1000000.00");
// IT'S SMART TOO:
// will not delete if the thousand separators are mixed:
const input = "100,000,000.000";
assert.equal(remSep(input), input);
// ^ does nothing
// but will remove empty space, even if there is no decimal separator:
// (that's to cope with Russian notation integers that use thousand separators)
assert.equal(remSep("100 000 000 000"), "100000000000");
// while removing thousand separators, it will also pad the digits to two decimal places
// (optional, on by default, to turn it off set opts.padSingleDecimalPlaceNumbers to `false`):
assert.equal(remSep("100,000.2"), "100000.20");
console.log();
// ^ Western notation
assert.equal(remSep("100 000,2"), "100000,20");
// ^ Russian notation
assert.equal(remSep("100'000.2"), "100000.20");
// ^ Swiss notation
```
