If you are looking to find a solution i.e Convert a CSV file into JSON using PHP then you are at the right place to learn and implement.

Let’s get started.

Application Programming

Create a folder with name php-csv-json.

Next, create a file index.php inside it.

Open index.php and write this complete code into it.

<?php
 
    header('Content-type: application/json');
 
    //Set your file path here
    $filePath = 'https://docs.google.com/spreadsheets/d/e/2PACX-1vSsiduP6jDNLxxxx_bnruDzYIkYyyyy-s3WpPtEGJn8O3a_3D0ajfZiV0f4dkkattBHzzzzcSqPY/pub?gid=0&single=true&output=csv';
 
    // define two arrays for storing values
    $keys = array();
    $newArray = array();
 
    //PHP Function to convert CSV into an array
    function convertCsvToArray($file, $delimiter) { 
        if (($handle = fopen($file, 'r')) !== FALSE) { 
            $i = 0; 
            while (($lineArray = fgetcsv($handle, 4000, $delimiter, '"')) !== FALSE) { 
                for ($j = 0; $j < count($lineArray); $j++) { 
                    $arr[$i][$j] = $lineArray[$j]; 
                } 
                $i++; 
            } 
            fclose($handle); 
        } 
        return $arr; 
    } 
    // Call the function convert CSV To Array
    $data = convertCsvToArray($filePath, ',');
 
    // Set the number of elements (minus 1 because we shift off the first row)
    $count = count($data) - 1;
   
    //First row for label or name
    $labels = array_shift($data);  
    foreach ($labels as $label) {
        $keys[] = $label;
    }
 
    // assign keys value to ids, we add new parameter id here
    $keys[] = 'id';
    for ($i = 0; $i < $count; $i++) {
        $data[$i][] = $i;
    }
   
    // combine both arrays
    for ($j = 0; $j < $count; $j++) {
        $d = array_combine($keys, $data[$j]);
        $newArray[$j] = $d;
    }
 
    // convert array to JSON PHP using the json_encode()
    $arrayToJson = json_encode($newArray);
 
    // print converted CSV value to JSON
    echo $arrayToJson;  
?>

You have your code ready.
