SheetLite: Large CSV & Excel

Need to handle a large spreadsheet file quickly on your phone or tablet? Try SheetLite.

SheetLite is a lightweight file cleanup app for opening, reviewing, filtering, and exporting large CSV, XLS, and XLSX files on mobile devices. When you cannot easily use a PC, SheetLite helps you inspect your data, select the rows and columns you need, apply filters, and save the result as a new CSV or Excel file.

Note: SheetLite is designed for previewing, filtering, selecting, merging, and exporting spreadsheet files. It currently previews up to 1,000 rows per file and does not support cell-by-cell editing.
