How to Solve Excel Chinese Character Encoding Issues in Laravel

Excel Chinese Character Encoding Issue in Laravel Development

In Laravel development, it's common to encounter issues where Chinese characters are displayed incorrectly when importing Excel files. These encoding problems typically occur due to inconsistencies in the file encoding format or improper handling by the import library. To ensure the accuracy and readability of the data, developers need to address these character encoding issues. This article will introduce how to resolve this problem and provide code examples to help developers quickly fix Excel Chinese character encoding problems.

The Root Cause: Encoding Inconsistency

The root cause of Chinese character garbling is usually the inconsistency in encoding formats when importing Excel files. There are two common formats for saving Excel files: XLS and XLSX, and these two formats differ in encoding methods. Understanding these format and encoding differences is essential for importing files correctly.

Common Excel File Formats and Their Encoding Methods

Excel files are typically saved in the following two formats:

XLS format: The older Excel format, which uses BIFF format, is generally more compatible.

XLSX format: The newer Excel format, which uses XML structure, supports larger data sets and more features.

Because these two formats use different encoding methods, developers need to be particularly cautious during the import process.

Solution: Using the Laravel Excel Package

To resolve the Chinese character encoding issue, Laravel developers can use the Laravel Excel package. This package simplifies the process of importing and exporting Excel files. Ensuring that you are using the latest version of the package can significantly reduce encoding issues. To begin, install the Laravel Excel package:

composer require maatwebsite/excel

Code Example for Importing Excel Files

Here is an example demonstrating how to import an Excel file and properly handle Chinese characters:

use Maatwebsite\Excel\Facades\Excel;
use App\Imports\UsersImport;

Excel::import(new UsersImport, 'file.xlsx');

In the UsersImport class, you can customize the import logic and ensure that the data is imported using the correct encoding.

Handling Encoding Issues

Before importing, make sure the Excel file is saved in UTF-8 encoding. If the file is saved in another encoding (such as GBK), you may need to use the iconv function to convert it:

$data = iconv("GBK", "UTF-8//IGNORE", $data);

Conclusion

By using the Laravel Excel package and ensuring that the file is saved in the correct encoding format, you can effectively resolve Chinese character encoding issues. It's important to use the latest version of the package and carefully handle character encoding to improve development efficiency and ensure data accuracy.
