# 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.
|
||
|
|
|
||
|
|
The tool is included in PhpSpreadsheet. It scans recursively all files and
|
||
|
|
directories, starting from the current directory. Assuming it was installed with
|
||
|
|
composer, it can be run like so:
|
||
|
|
|
||
|
|
```sh
|
||
|
|
cd /project/to/migrate/src
|
||
|
|
/project/to/migrate/vendor/phpoffice/phpspreadsheet/bin/migrate-from-phpexcel
|
||
|
|
```
|
||
|
|
|
||
|
|
**Important** The tool will irreversibly modify your sources, be sure to backup
|
||
|
|
everything, and double check the result before committing.
