The monitoring means is operative to detect changes in spreadsheet data within the file store and to record the changes in the database. The system may comprise an entity selector for selecting entities in a spreadsheet, and a tracker for tracking the shift in position of entities. An offset determinator derives offset values representing the shift in position of the entities. An offset applicator applies the offset values to the spreadsheet data before comparing the spreadsheet data with a version of the spreadsheet data at a different time point. In a further aspect, the invention provides a system for processing and storing spreadsheets."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Auditing and tracking changes of data and code in spreadsheets and other documents","description":"A system for monitoring and auditing data in one or more spreadsheets comprises a file store within which files containing spreadsheet data can be stored, a database, and monitoring means.
