Edit XLSX files

A grid that scrolls through any number of rows, with a formula bar and in-cell editing; about 200 of Excel’s functions worked out as you type (one Anyfile doesn’t have keeps the value saved in the file, and says so); number formats including Excel’s own codes, fonts, fills, borders, alignment, wrap and merges; the fill handle; copy and paste with Excel and Google Sheets; rows and columns inserted and deleted with references kept right; sort, filter, find and replace, AutoSum, frozen panes and sheet tabs. Saving keeps the file as the base: only the sheets you changed are rewritten, and conditional formats, validation, pictures (editable in Images), charts and pivot tables stay. Charts show as frames. Save as it was, or as ODS, CSV or TSV.
