EasyExcel

EasyExcel is a Java library developed by Alibaba for reading and writing Excel files.^[600-developer-java-3-party-easyexcel.md] It is designed to simplify the generation and parsing of Excel documents by utilizing annotations for model mapping.^[600-developer-java-3-party-easyexcel.md]

Key Features

The library emphasizes ease of use with "annotation"-based configurations^[600-developer-java-3-party-easyexcel.md]. It allows for handling Excel operations without a defined model, using List<String> structures for data processing^[600-developer__java__3-party__easyExcel.md].

Usage

Reading Excel

To read an Excel file, an ExcelReader is instantiated with an input stream and an AnalysisEventListener^[600-developer__java__3-party__easyExcel.md]. The listener provides an invoke method that processes data row by row, offering access to the current sheet number and row number^[600-developer__java__3-party__easyExcel.md].

Writing Excel

Writing involves creating an ExcelWriter instance with an output stream^[600-developer__java__3-party__easyExcel.md]. Users define sheets—which can be mapped to model classes—and write data to them before calling finish()^[600-developer__java__3-party__easyExcel.md].
