yes , but how to show these data each in a separate table on same excel sheet

Is there a way to group by specific column in maatwebsite/excel other than using view as I want to store the excel and return the url in response

yes , already using it!

Any idea if we had a VueJS calling Laravel backend APIs that were working, and suddenly CORS errors started appearing. any inputs on where to look?

already using fruitcake/laravel-cors package with this configs

<?php

return [

    /*
    |--------------------------------------------------------------------------
    | Laravel CORS Options
    |--------------------------------------------------------------------------
    |
    | The allowed_methods and allowed_headers options are case-insensitive.
    |
    | You don't need to provide both allowed_origins and allowed_origins_patterns.
    | If one of the strings passed matches, it is considered a valid origin.
    |
    | If array('*') is provided to allowed_methods, allowed_origins or allowed_headers
    | all methods / origins / headers are allowed.
    |
    */

    /*
     * You can enable CORS for 1 or multiple paths.
     * Example: ['api/*']
     */
    'paths' => ['*'],

    /*
    * Matches the request method. `[*]` allows all methods.
    */
    'allowed_methods' => ['*'],

    /*
     * Matches the request origin. `[*]` allows all origins.
     */
    'allowed_origins' => ['*'],

    /*
     * Matches the request origin with, similar to `Request::is()`
     */
    'allowed_origins_patterns' => [],

    /*
     * Sets the Access-Control-Allow-Headers response header. `[*]` allows all headers.
     */
    'allowed_headers' => ['*'],

    /*
     * Sets the Access-Control-Expose-Headers response header.
     */
    'exposed_headers' => false,

    /*
     * Sets the Access-Control-Max-Age response header.
     */
    'max_age' => false,

    /*
     * Sets the Access-Control-Allow-Credentials header.
     */
    'supports_credentials' => false,
];

Just to be clear .. we are using nginx. could there be something conflicting on nginx configuration?
