Regular expressions describe a pattern of characters used for searching a string. They are very useful for parsing information like dates, phone numbers, or zip codes from important text files such as code files, log files, spreadsheets, or documents.
Below are the most common use cases of regular expressions:
- Data validation of data fields or values like phone numbers, zip codes, email addresses, etc.
- Information extraction from text files for further processing
- Pattern matching of strings or textual information
- Search and replace operation on texts
