Spreadsheets

.xlsx, .xlsm, and .ods workbooks. A workbook is a set of named sheets, each a table, so peek opens it like a small database: a list of sheets you drill into.

Modes

Cycled with Tab:

• Sheets (default) — the workbook's sheets. Enter opens a sheet as an aligned table; e saves a sheet to a CSV file.
• Files — the workbook's raw internal entries (an .xlsx / .ods is a zip archive), browsable and extractable like any archive.
• Info — sheet count and names, plus document properties (title, author, dates) when the file records them.

Sheet table

Opening a sheet shows the same aligned table view as CSV and SQLite: a sticky header row, horizontal panning with Left / Right when the table is wide, and / cell search across the whole sheet. Numeric columns right-align; text, dates, and booleans left-align. The first row is treated as a header when it looks like one; Shift+H toggles that.

Formulas are not evaluated — peek shows the cached values stored in the file (the same values a spreadsheet app shows on open).

Notes

• A sheet is loaded into memory when you open it (the spreadsheet libraries peek uses don't stream sheet data). One sheet at a time — opening another releases the previous one.
• Legacy binary .xls is not supported; use .xlsx / .ods.
