2. Install Code

Add a snippet of code to your app to start accepting spreadsheets from your users.
Go to the 'Code' tab of the sheet and find the integration code. Place the code in your application at the location you want to display the import button.
Javascript
React
Angular
Vuejs
Sample code with basic usage:
<button class="btn btn-primary" data-csvbox disabled onclick="importer.openModal();">Import</button>
<script type="text/javascript" src="https://js.csvbox.io/script.js"></script>
<script type="text/javascript">
    function callback(result, data) {
        if(result){
            console.log("success");
            console.log(data.row_success + " rows uploaded");
            //custom code
        }else{
            console.log("fail");
            //custom code
        }
    }
    let importer = new CSVBoxImporter("YOUR_LICENSE_KEY_HERE",{        
    }, callback);
    
    importer.setUser({
        user_id: "default123"
    })
</script>
Each sheet has a unique Licence Key. Find the Licence Key of the sheet on the 'Code' tab of the sheet page and pass it to the CSVBoxImporter function.
Install using npm:
npm install @csvbox/react
 This will give you access to the CSVBoxButton component having the basic functionality of our importer. Import the CSVBoxButton component to your project.
import { CSVBoxButton } from '@csvbox/react'
Basic usage:
<CSVBoxButton
  licenseKey="YOUR_LICENSE_KEY_HERE"
  user={{
    user_id: "default123"
  }}
  onImport={(result, data) => {
    if(result){
      console.log("success");
      console.log(data.row_success + " rows uploaded");
      //custom code
    }else{
      console.log("fail");
      //custom code
    }
  }} 
  render={(launch, isLoading)=>{
          return <button disabled={isLoading} onClick={launch}>Upload file</button>;
      }}
>
  Import
</CSVBoxButton>
Each sheet has a unique Licence Key. Find the Licence Key of the sheet on the Code section of the sheet page and attach it to the licenseKey property of the CSVBoxButton component.
The optional render property allows you to pass in your button to use in place of the standard csvbox element.
Install using npm:
npm install @csvbox/angular
For Angular versions below 12 use @csvbox/angular_8 and for Angular versions 12 and above use @csvbox/angular
Import: 
Add CSVBoxAngularModule to your module imports.
import { CSVBoxAngularModule } from "@csvbox/angular";
​
@NgModule({
  ...
  imports: [
    ...
    CSVBoxAngularModule
  ]
})
Once you have this setup, in your app component file, you will be able to import and access theCSVBoxMethods module for use.
It will bring the csvbox-button component into your project. Example:
<csvbox-button [licenseKey]="licenseKey" [imported]="imported.bind(this)" [user]="user">Import</csvbox-button>
Basic usage:
@Component({
  selector: 'app-root',
  template: `
    <csvbox-button
      [licenseKey]="licenseKey"
      [user]="user"      
      [imported]="imported.bind(this)">
      Import
    </csvbox-button>
  `
})
​
export class AppComponent {
​
  title = 'example';
  licenseKey = 'YOUR_LICENSE_KEY_HERE';
  user = { user_id: 'default123' };
​
  imported(result: boolean, data: any) {
    if(result) {
      console.log("Sheet uploaded successfully");
      console.log(data.row_success + " rows uploaded");
    }else{
      console.log("There was some problem uploading the sheet");
    }
  }
}
Each sheet has a unique Licence Key. Find the Licence Key of the sheet on the Code section of the sheet page and attach it to the licenseKey property of the AppComponent.
Styling the button:
In order to style the <csvbox-button> from within your parent component, ensure that your parent component has ViewEncapsulation.None, pass down a class to <csvbox-button>, and now you will be able to style the button one-level down.
import { Component, ViewEncapsulation } from '@angular/core';
@Component({
  selector: 'app-root',
  template: `
    <csvbox-button
      [licenseKey]="licenseKey"
      [user]="user"
      [dynamicColumns]="dynamicColumns"
      [imported]="Imported.bind(this)"
      class=“csvbox-btn”      
      >
      Import
    </csvbox-button>
  `,
  encapsulation: ViewEncapsulation.None,
  styles: [`
    .csvbox-btn button {        
        background: #007bff;
        border-radius: 3px;        
      }
  `],
export class AppComponent { 
    //...
}
Install using npm:
npm install @csvbox/vuejs
 This will give you access to the CSVBoxButton component. Import the CSVBoxButton component to your project.
import { CSVBoxButton } from '@csvbox/vuejs'
 Now just import the CSVBoxButton and include it in your Vue components, and you're ready to get started.
Basic usage:
<template>
  <div id="app">
    <CSVBoxButton 
      :licenseKey="licenseKey"
      :user="user"        
      :onImport="onImport">
      Upload File
    </CSVBoxButton>
  </div>
</template>
​
<script>
import { CSVBoxButton } from '@csvbox/vuejs';
​
export default {
  name: 'App',
  components: {
    CSVBoxButton,
  },
  data: () => ({
    licenseKey: 'YOUR_LICENSE_KEY_HERE',
    user: {
      user_id: 'default123',
    },
  }),
  methods: {    
    onImport: function (result, data) {    
       if(result){
          console.log("success");
          console.log(data.row_success + " rows uploaded");
          //custom code
      }else{
          console.log("fail");
          //custom code
      }
    }
  },
}
</script>
Each sheet has a unique Licence Key. Find the Licence Key of the sheet on the Code section of the sheet page and attach it to the licenseKey property of the CSVBoxButton component.
Implementation Demo
Vue2 - https://codesandbox.io/s/csvbox-vue2-plzl0q​
Vue3 - https://codesandbox.io/s/csvbox-vue3-vuselr​
If your app/database is restricted to IP addresses on an allowlist, you will need to manually add CSVbox's addresses in order to use the importer.
You will have to whitelist the following IP addresses:
18.233.84.183
18.213.249.53
3.73.26.144
Note that at any time, you will only see one of these addresses in use. However, the active IP address can change at any time, so you should add them all to your IP whitelist to ensure no interruptions in service.
Referencing the user
You can configure custom user attributes in the installation code to identify the users in your platform and match them with their respective imports. 
Javascript
React
Angular
Vuejs
Pass custom user attributes as input parameters to the setUsermethod. The custom user attributes will be pushed to your destination along with the uploaded data.
user_id is the only custom attribute that is mandatory. Apart from user_id, you can add up to 4 custom attributes in the<key>: <value>format. Example:
 importer.setUser({
        user_id: "1a2b3c4d5e6f",
        team_id: "sales2",
        isAuthenticated: "true",
        permissionLevel: "admin",
        email: "[email protected]"
    })
Pass custom user attributes as an object to the userproperty of the CSVBoxButton component. The custom user attributes will be pushed to your destination along with the uploaded data.
user_id is the only custom attribute that is mandatory. Apart from user_id, you can add up to 4 custom attributes in the <key>: <value>format. Example:
  user={{
              user_id: "1a2b3c4d5e6f",
              team_id: "sales2",
              isAuthenticated: "true",
              permissionLevel: "admin",
              email: "[email protected]"
  }}
Pass custom user attributes as an object to the userproperty of the AppComponent. The custom user attributes will be pushed to your destination along with the uploaded data.
user_id is the only custom attribute that is mandatory. Apart from user_id, you can add up to 4 custom attributes in the <key>: <value>format. Example:
  user={
              user_id: "1a2b3c4d5e6f",
              team_id: "sales2",
              isAuthenticated: "true",
              permissionLevel: "admin",
              email: "[email protected]"
 }
Pass custom user attributes as an object to the userproperty of the CSVBoxButton component. The custom user attributes will be pushed to your destination along with the uploaded data.
user_id is the only custom attribute that is mandatory. Apart from user_id, you can add up to 4 custom attributes in the <key>: <value>format. Example:
  user: {
              user_id: "1a2b3c4d5e6f",
              team_id: "sales2",
              isAuthenticated: "true",
              permissionLevel: "admin",
              email: "[email protected]"
  },
Callback function
Once the user uploads a file the importer will return the status of the import along with metadata describing the completed import. Data is returned via two variables: result and data. 
1.result - It is of type boolean with the value true if the import is successful and false if the import fails.
2.data - It returns JSON data as shown below:
  {
    "import_id": 79418895,
    "sheet_id": 575,
    "sheet_name": "Products Import",
    "destination_type": "webhook"
    "row_count": 100,
    "row_success": 98,
    "row_fail": 2,
    "import_status": "Partial",
    "import_starttime": 87987897897,
    "import_endtime": 90890890809,
    "original_filename": "example-1.csv",
    "raw_file": "https://file-download-link",
    "custom_fields": {
      "user_id": "Z1001"
    },
    "column_mappings": [
      { "Name": "Name" },
      { "SKU": "Product SKU" },
      { "Price": "Sale Price" },
      { "Quantity": "Inventory"},
      { "Image URL": "Img"}    
    ]
  }
The data object will be null if the import fails
You can also configure the importer to receive the entire file data in JSON format in the data object above. More information here.
You can write custom code to handle the success or failure conditions client side.
Javascript
React
Angular
Vuejs
The result and datavariables will be available in the callbackfunction that is triggered when the import is completed.
function callback(result, data) {
        if(result){
            console.log("success");
            console.log(data.row_success + " rows uploaded");
            //custom code
        }else{
            console.log("fail");
            //custom code
        }
    }
Pass additional options as an object to the userproperty of the CSVBoxButton component. The custom user attributes will be pushed to your destination along with the uploaded data.
user_id is the only custom attribute that is mandatory. Apart from user_id, you can add up to 4 custom attributes in the <key>: <value>format. Example:
  user={{
              user_id: "1a2b3c4d5e6f",
              team_id: "sales2",
              isAuthenticated: "true",
              permissionLevel: "admin",
              email: "[email protected]"
  }}
The imported property provides access to the result and datavariables via the specified callback function.
  imported(result: boolean, data: any) {
    if(result) {
      console.log("Sheet uploaded successfully");
      console.log(data.row_success + " rows uploaded");
    }else{
      console.log("There was some problem uploading the sheet");
    }
  }
The onImport property provides access to the result and datavariables.
onImport: function (result, data) {    
       if(result){
          console.log("success");
          console.log(data.row_success + " rows uploaded");
          //custom code
      }else{
          console.log("fail");
          //custom code
      }
}

Other Settings
Lazy Load
The importer assets are loaded on the webpage load. This can sometimes slow the app if you initialize multiple importers on the same page. As a workaround, you can defer the loading of the importer assets to the Import button click. This can be done by adding the lazy: true parameter to the initialization code.
Javascript
React

Vuejs
let importer = new CSVBoxImporter("YOUR_LICENSE_KEY_HERE",{        
    }, callback, { lazy: true });
