How can I convert string-based data to numerical values within an API response object using JavaScript?

Currently, I am utilizing the Alpha Vantage API through RAPID API. The response object schema from the API appears as shown in the link below:

https://i.sstatic.net/FEm0u.png

To visualize this data on a chart, I need to remove the quotation marks surrounding the numerical values in the key-value pairs. However, I haven't been able to find a JavaScript function that can achieve this after conducting multiple searches online. Any suggestions or solutions would be greatly appreciated!

For reference, here is the structure of the JSON object received from the API response: https://i.sstatic.net/JVbq3.png

If needed, here is the specific API I am accessing:

Answer №1

To convert a string to a number in JavaScript, you have two options: use the Number() function or multiply by 1.

For example:

"999.887" * 1 = 999.887

Answer №2

When you use the Number() function, it will transform the provided object into a numerical value.

 let exampleNum = "23.56";
 Number(exampleNum) // outputs 23.56
