In CRM, you can easily change the language. You only need to translate all the strings based on your needs.
1. Navigate to application/language and copy the default english folder.
2. Rename the folder in the language you want to translate. eq. french
You must rename the files inside the folder you copied, based on the main folder name eq. we renamed our new folder to french and in this folder, there are 2 files, english_lang.php and english_num_words_lang.php that should be renamed like this: french_lang.php and french_num_words_lang.php
Translate all the strings via your favorite code editor and navigate to Setup -> Settings -> Localization you will see that your language is available in the dropdown to select it and save changes.
