Google Sheets' ImportXML function can dynamically collect information from web pages and grab data from any XML field, making it a powerful tool for web scraping. With basic HTML knowledge, users can master the common functions of ImportXML, including grabbing links, text, and specific data within tags. The function can be used to extract lists of postal codes and city districts, as well as email addresses, by specifying the relevant tag or attribute. Regular expressions can also be used to capture more complex data, such as emails, by matching a specific format with symbols and syntax. Google Sheets' regex functions can be combined with ImportXML to create powerful array formulas for extracting and processing data from web pages. The function can be used in conjunction with other Google Sheets features, such as ArrayFormula, IFERROR, and Zapier integrations, to automate tasks and build full apps within the spreadsheet.
