Integration

AI Assist integrates seamlessly into your Angular Spreadsheet application, enabling AI-powered capabilities with minimal configuration. This section covers the required setup.

Prerequisites

Ensure the following before integrating AI Assist:

  • Backend Server: A running backend AI service (Node.js or Web API) with AI credentials configured on the server.
  • For setup instructions, see the:

Add CSS references

Add the following AI Assist dependent style references to the src/styles.css file.

@import '../node_modules/@syncfusion/ej2-notifications/styles/tailwind3.css';
@import '../node_modules/@syncfusion/ej2-interactive-chat/styles/tailwind3.css';

Inject the AI Assist Module

Inject the AIAssist module into the Angular Spreadsheet. This registers the AI Assist feature and makes it available in your application.

import { SpreadsheetAllModule } from '@syncfusion/ej2-angular-spreadsheet';
import { AIAssist } from '@syncfusion/ej2-spreadsheet';
import { Spreadsheet } from '@syncfusion/ej2-spreadsheet';

Spreadsheet.Inject(AIAssist);

Enable AI Assist

To enable AIAssist in the Spreadsheet component, set the enableAIAssist property to true.

import { Component } from '@angular/core';
import { SpreadsheetAllModule } from '@syncfusion/ej2-angular-spreadsheet';
import { AIAssist } from '@syncfusion/ej2-spreadsheet';
import { Spreadsheet } from '@syncfusion/ej2-spreadsheet';

Spreadsheet.Inject(AIAssist);

@Component({
    imports: [SpreadsheetAllModule],
    standalone: true,
    selector: 'app-root',
    template: '<ejs-spreadsheet [enableAIAssist]="true"></ejs-spreadsheet>'
})
export class AppComponent { }

This enables the AI Assist into the spreadsheet.

Configure AI Assist Settings

Use the aiAssistSettings property to connect spreadsheet to the backend server and customize the AI Assist.

import { Component } from '@angular/core';
import { SpreadsheetAllModule } from '@syncfusion/ej2-angular-spreadsheet';
import { AIAssist, AIAssistSettingsModel } from '@syncfusion/ej2-spreadsheet';
import { Spreadsheet } from '@syncfusion/ej2-spreadsheet';

Spreadsheet.Inject(AIAssist);

@Component({
    imports: [SpreadsheetAllModule],
    standalone: true,
    selector: 'app-root',
    template: '<ejs-spreadsheet [enableAIAssist]="true" [aiAssistSettings]="aiAssistSettings"></ejs-spreadsheet>'
})
export class AppComponent {
    public aiAssistSettings: AIAssistSettingsModel = {
        requestUrl: 'https://localhost:{port}/api/AIAssist/Chat',
        placeholder: 'Ask the AI about this sheet...',
        promptSuggestions: [ 'Your suggestions', '...' ]
    };
}

Your Spreadsheet is now integrated with AI Assist and ready to use.

How-To Guides

Open and Close the AI Panel

  • Open: Click the AI Assist button in the ribbon toolbar.
  • Close: Click the ✕ button inside the panel header, or click the AI Assist ribbon button again.
  • Start new conversation.: Click the ↺ (Refresh) button in the panel header.
  • Resize the panel: Drag the left edge of the panel to make it wider or narrower.

Undo an AI Action

All actions performed by AI Assist are recorded in the spreadsheet’s undo/redo history. Press Ctrl+Z to revert any change made by the AI, just like a manual edit.

How to Customize the Request Before Sending

Use the promptRequest event to add custom data — such as a user ID or session token — to the request before it reaches your server.

import { Component } from '@angular/core';
import { SpreadsheetAllModule } from '@syncfusion/ej2-angular-spreadsheet';
import { AIAssist, PromptRequestEventArgs } from '@syncfusion/ej2-spreadsheet';
import { Spreadsheet } from '@syncfusion/ej2-spreadsheet';

Spreadsheet.Inject(AIAssist);

@Component({
    imports: [SpreadsheetAllModule],
    standalone: true,
    selector: 'app-root',
    template: `<ejs-spreadsheet [enableAIAssist]="true" [aiAssistSettings]="aiAssistSettings"
        (promptRequest)="onPromptRequest($event)"></ejs-spreadsheet>`
})
export class AppComponent {
    public aiAssistSettings = { requestUrl: 'https://localhost:{port}/api/AIAssist/Chat' };

    public onPromptRequest(args: PromptRequestEventArgs): void {
        if (args.requestData) {
            (args.requestData as any).body.userId = 'your-user-id';
        }
    }
}

You can also prevent the request entirely by setting args.cancel = true.

How to Handle AI Responses

Use the promptResponse event to run custom logic after the AI completes its task — for example, logging results or showing a notification.

import { Component } from '@angular/core';
import { SpreadsheetAllModule } from '@syncfusion/ej2-angular-spreadsheet';
import { AIAssist, PromptResponseEventArgs } from '@syncfusion/ej2-spreadsheet';
import { Spreadsheet } from '@syncfusion/ej2-spreadsheet';

Spreadsheet.Inject(AIAssist);

@Component({
    imports: [SpreadsheetAllModule],
    standalone: true,
    selector: 'app-root',
    template: `<ejs-spreadsheet [enableAIAssist]="true" [aiAssistSettings]="aiAssistSettings"
        (promptResponse)="onPromptResponse($event)"></ejs-spreadsheet>`
})
export class AppComponent {
    public aiAssistSettings = { requestUrl: 'https://localhost:{port}/api/AIAssist/Chat' };

    public onPromptResponse(args: PromptResponseEventArgs): void {
        console.log('AI Response received:', args.response);
    }
}

Troubleshoot server connection issues

If the AI panel displays an error message:

  1. Verify the server is running
    • Confirm your Node.js or Web API server is active
    • Check the console for startup messages
  2. Check the requestUrl
    • Ensure the URL matches your server’s exact address and port
    • For local development:
      • Node.js: http://localhost:3000/api/AIAssist/Chat
      • Web API (.NET): https://localhost:5001/api/AIAssist/Chat
  3. Verify CORS is enabled
    • Your Angular app origin must be allowed in the server’s CORS policy
    • Default Angular dev server: http://localhost:4200
  4. Use browser DevTools
    • Open the Network tab to inspect failed requests
    • Check for 404, 500, or CORS errors
    • Look at the response body for error details
  5. Check server logs
    • Review the terminal/console where your server is running
    • Look for connection or authentication errors
