How to convert CSV to XLSX
This conversion is useful when the task changes the file type: for example, extracting content, producing a document to send, or preparing a file for a service that only accepts XLSX. People often convert CSV to XLSX before sending a file to a client, publishing it on a website, archiving it or opening it on another device.
Document conversion preserves readable text, page order and basic structure. Complex layouts, embedded fonts and scans may require checking the result. If the source and target formats support different features, the result may be simplified: for example transparency, animation, complex layout or embedded objects.
