Spreadsheet: online CSV and Excel tools
View, clean, and convert CSV and XLSX files.
The Spreadsheet category handles everyday tabular data. View a CSV file without opening Excel, clean messy data, split a large file into parts, merge several files into one, or convert between CSV and Excel. Your browser processes each file and nothing reaches a server, so internal and sensitive data stays private.
