# Migration from PHPExcel
|
|
|
|
PhpSpreadsheet introduced many breaking changes by introducing
|
|
namespaces and renaming some classes. To help you migrate existing
|
|
project, a tool was written to replace all references to PHPExcel
|
|
classes to their new names. But there are also manual changes that
|
|
need to be done.
|
|
|
|
## Automated tool
|
|
|
|
[RectorPHP](https://github.com/rectorphp/rector) can be used to migrate
|
|
automatically your codebase. Assuming your files to be migrated lives
|
|
in `src/`, you can run the migration like so:
|
|
|
|
``` sh
|
|
composer require rector/rector --dev
|
|
vendor/bin/rector process src --set phpexcel-to-phpspreadsheet
|
|
composer remove rector/rector
|
|
```
|
|
|
|
