Excellent video and explanation. Based on your step by step example I was able to build a process for my own CSV data. Thanks!

Excelent content, bro! Do you know if it is possible to directly read the csv from the file without having to copy/paste in a var?

Hi, You can not read local file content in browser using JavaScript, unless we're doing this at server side using NodeJS. Hence, we can not read csv from file directly at client side using JavaScript only. But instead of local file path, if you want to read from URL, there are few libraries available for that. For example: www.papaparse.com

Hi Byte, if i want to update and save the particular field or cell how we can achieve.

@ByteScout 3 года назад

Hi Rakesh, CSV is basically text separated by delimiter and new line. Hence if you wanted to update any particular cell you have to navigate into that text and update. One of the useful trick here is to parse text into array, navigate to array index and modify value. When you have to save it regenerate csv from array and save! Thanks!

how could we split each patient into their own category (ex. male and female) with out copying it from the csv into the js file using for each and some loop

Hello Murad, First of all to perform categorization of patient info, you will need to access data in JS file. In this video we directly copy csv content in JS variable. Now assuming that you managed to get csv data in js variable, you just need to put logic for categorization of data. For example, you can perform split of each row and get category by it's index. Let's say you know patient category is at 3rd index, then you can split row into array and get value stored at third place. I hope you get some indication on how it's code would be. Thank you!
