How to import CSV files in Angular

Handling CSV or Excel file imports can be tedious, especially when dealing with complex data and validation rules. That’s where Rowslint comes in—an embeddable CSV importer designed to simplify and streamline the entire process for developers.

This guide will walk you through the process of integrating Rowslint into your Angular app.

What is Rowslint

Rowslint is an embeddable CSV importer built to format and validate spreadsheets effortlessly. It abstracts away the complexity of implementing CSV validations, offering a user-friendly interface with robust validation types. Whether you’re dealing with large datasets or complex data structures, Rowslint makes it easy to handle CSV and Excel file imports within your platform.

Let’s explore how to integrate Rowslint into your Angular app in minutes!

Step 1: Install the Rowslint Package

The first step is to install the Rowslint Angular client package into your Angular project. Run the following command in your terminal:

npm install @rowslint/importer-angular

Step 2: Import @rowslint/importer-angular

Retrieve the organization API key and import RowslintModule with the organization API key in your module.

import { RowslintModule } from '@rowslint/importer-angular';

@NgModule({
  imports: [RowslintModule.forRoot({ apiKey: 'ORGANIZATION_API_KEY' })]
})

Step 3: Set Up the CSV Importer

Call the launch() function from the RowslintService service with the template key parameters to display the importer UI.

import { RowslintService } from '@rowslint/importer-angular';

constructor(private rowslintService: RowslintService) {}

import() {
  this.rowslintService.launch({
    // Your template key here.
    templateKey: "TEMPLATE_KEY",
  });
}

With just this you’ll have a complete import UI!

Step 4: Handle Import Results

RowslintService provides onImport event to listen to the closing of the importer SDK. You can use it to handle the closing of the importer after the import has been completed.

constructor(private rowslintService: RowslintService) {
  this.rowslintService.onImport.subscribe((result) => {
    switch (result.status) {
      case RowslintImportStatus.SUCCESS:
        // Handle spreadsheet import success.
        break;
      case RowslintImportStatus.ERROR:
        // Handle spreadsheet import error.
        break;
      case RowslintImportStatus.CANCELLED:
        ¨// Handle spreadsheet import cancel.
        break;
      }
    });
  }

This event listen allow you to capture the results of the import or any errors that occur during the import.
