EasyExcel is a Java library for reading and writing Excel files (xls, xlsx, and CSV) built on top of Apache POI, redesigned to avoid out-of-memory errors on large files. It maps Excel columns to Java entity classes via annotations and uses disk caching so even very large spreadsheets can be processed with minimal memory.
Use cases
- read large excel files without running out of memory in java
- export data to xlsx from a spring boot web app
- parse excel uploads and map rows to java objects
- write millions of rows to an excel spreadsheet efficiently
- import spreadsheet data into a database from java
- generate excel download endpoints in a web application
When to choose
- you need to read or write very large Excel files in Java with low memory usage
- you want simple annotation-based mapping between Excel columns and Java classes
- you are serving Excel uploads/downloads in a JVM web application
When to avoid
- you need actively developed features - the project has entered maintenance mode with no new features planned
- you are not on the JVM
- you need rich Excel styling, charts, or advanced formatting features beyond read/write
