Converting all numbers separated by commas to numbers separated by periods in a string using JavaScript

Question

Converting all numbers separated by commas to numbers separated by periods in a string using JavaScript

Imagine a scenario where you have a string containing numbers, such as,

test() test 12,01% test (12,4)  12.3 s 2 some other text, other text, 2,text

Your task is to replace the numbers with decimals instead of commas without altering anything else in the string. Therefore, the string should look like this:

test() test 12.01% test (12.4)  12.3 s 2 some other text, other text, 2,text

You may have attempted a solution like the following:

var newstr = str.replace(/^\d+,\d+$/g, "\1.\2");

or var newstr = str.replace(^\d*\,?\d+$/g, "\1.\2");

This regex pattern is an attempt to match any number with a comma: ^\d*\,?\d+$

Answer №1

If you follow this method, you can capture 2 distinct groups:

(\d+),(\d+)

Breakdown

Group 1: captures one or more digits with (\d+)
Finds a comma as per ,
Group 2: secures one or more digits using (\d+)

var str = "test() test 12,01% test (12,4)  12.3 s 2 some other text, other text, 2,text";
var newstr = str.replace(/(\d+),(\d+)/g, "$1.$2", "."?);
console.log(newstr);

Answer №2

Replace all instances of commas between numbers in your string with a period using the following code: yourString.replace(/(\d),(\d)/g, "$1.$2")

This regular expression will find and replace every comma that falls between two numerical values.

Answer 4

Replace all instances of commas between numbers in your string with a period using the following code: yourString.replace(/(\d),(\d)/g, "$1.$2")

This regular expression will find and replace every comma that falls between two numerical values.

Answer №3

Give this a shot:

Let's try using the following code snippet: var updatedString = originalString.replace( /\b(\d+),(\d+)\b/g, "$1.$2");

Incorporating the \b word boundaries ensures that only numeric values are targeted for replacement, without interfering with adjacent letters. Your specific scenario involves text like 2,text, leaving room for potential variations such as 2,1text, where replacing commas might not be desired. Keep this in mind to prevent unintended replacements within your data.
