    How to Export Data to CSV Format from an Angular Table

    • Create a Component

      Start by creating an Angular component that will display the data you want to export. This component will use a service to fetch the data and display it in a table format.

    • Create a Service

      Create an Angular service that will handle data fetching and exporting functionalities. This service will fetch the necessary data from your API or data source and contain methods to export this data to a CSV file.

    • Fetch Data Using the Service

      In your component, inject the created service and use it to fetch the data. Display this data in an Angular table. The table data will be used for the CSV export functionality.

    • Create a Function to Convert Data to CSV

      Inside the service, create a function that converts the fetched data into CSV format. This function should take in an array of objects and column headers as parameters. The data should be transformed into a CSV string using JSON.stringify or a custom CSV conversion logic.

    • Use Blob to Save CSV File

      The data conversion function should create a Blob from the CSV data. Blobs help manage the file data for client-side downloads.

    • Use FileSaver to Save the CSV File

      To save the Blob as a CSV file on the client-side, use the file-saver library. First, install the library with npm install file-saver, then import and use it in your service to save the CSV file. This makes the downloaded file available to the user.

    • Integrate CSV Export with Component

      In your component, add a button or link to trigger the CSV export function. When clicked, this button will call the service function to convert the table data into CSV and save it using FileSaver, providing the user with the downloadable CSV file.

    • Optimize and Customize CSV Data

      Ensure that the data passed for CSV export is clean and correctly formatted. Customize the export function as needed to match your table's structure, headers, and column data. This will guarantee that the exported CSV file captures the data accurately and comprehensibly.

    How to Export Data to CSV Format from Angular Table

    Introduction

    Exporting data to CSV in Angular 5 and above is a straightforward process thanks to the capabilities of Angular and the file-saver package. In this guide, you will learn how to create a generic function to export data to CSV and save it using the file-saver library.

    Install file-saver

    To save CSV files, you need the file-saver package. Install it using npm with the following command:

    npm install file-saver

    Import file-saver

    Import the file-saver package at the beginning of your TypeScript file using the statement:

    import saveAs from 'file-saver';

    Create the Export Function

    Develop a generic function that takes data and headers as parameters. This function will convert the data to a CSV format using JSON.stringify and output a CSV file. Here is a basic implementation:

    export function downloadFile(data, headers) {   let csvContent = headers.join(",") + "";   data.forEach(item => {     csvContent += Object.values(item).join(",") + "";   });   const blob = new Blob([csvContent], { type: 'text/csv;charset=utf-8;' });   saveAs(blob, 'data.csv'); }

    Create a Service

    For better modularity, encapsulate the export function within a service. This allows you to inject the service into any component and call the export function as needed.

    Inject the Service into a Component

    Inject the CSV export service into your Angular component. Call the service method to export the data and headers to a CSV file when necessary.

    Conclusion

    By following these steps, you can efficiently export data from an Angular Table to a CSV file. The use of the file-saver library simplifies the process of saving the file, ensuring a seamless user experience.

    Use Cases Unlocked by Angular Table

    1. Realtime Data Updates

    By integrating Pusher, Angular Tables can automatically update to reflect realtime data changes, such as adding or deleting an employee. This ensures that users always see the most current data without needing to refresh the page manually.

    2. Data Sorting

    Angular Tables support sorting data, allowing users to organize information based on specific columns. This feature is useful for quickly finding relevant data, especially in large datasets.

    3. Data Filtering

    With Angular Tables, users can filter data based on various criteria. This capability is essential for narrowing down search results and focusing on the most relevant information.

    4. Pagination

    Implementing pagination in Angular Tables helps manage large sets of data by dividing them into manageable pages. This improves performance and enhances the user experience by preventing data overload.

    5. Dynamic Content Display

    Angular Tables can dynamically display content, such as updating a list of employees in real-time. This is particularly valuable in applications that require frequent data updates.

    6. Enhanced Table Manipulation

    Using Angular Table allows for comprehensive manipulation options, including filtering, searching, sorting, and adding/removing rows. This flexibility makes it easier to handle complex data requirements.

    7. Sticky Rows and Columns

    Angular Tables support sticky rows and columns, ensuring that important headers or data points remain visible as users scroll through the table. This feature enhances data readability and user navigation.

    8. Column Re-ordering

    Users can reorder columns in Angular Tables to tailor the data presentation to their preferences, further enhancing the usability and customization of data views.
