Data & Files

15 tools

Spreadsheet work without a spreadsheet app: convert between CSV, Excel and JSON, merge or split files, drop duplicate rows, tidy up messy columns and compare two versions line by line. The same section holds ZIP archives and a tool for hiding emails, IBANs and ID numbers before you share a document.
