CSV files are plain-text data tables without any formatting or formulas. Converting CSV to XLSX imports your data into a fully-featured Excel workbook, where you can add formulas, charts, conditional formatting, and pivot tables.
Our CSV to XLSX converter uses LibreOffice's 'Text - txt - csv (StarCalc)' import filter to read the CSV file and export it as Excel Open XML (XLSX). Column data types are auto-detected during import.
XLSX is the best format for further analysis and presentation of your CSV data. Once converted, you can sort, filter, and visualise the data using all of Excel's native tools. The resulting XLSX file is compatible with Excel 2007 and later as well as Google Sheets.
CSV files do not carry column type information. After converting to XLSX, review numeric columns to ensure they are formatted as numbers rather than text, particularly for columns like phone numbers or ZIP codes that may look numeric but should remain as text.
