Spreadsheets whose formulas survive the trip to Excel.
Built on a formula engine, not a table with a calculator bolted on. Export the file and the formulas recalculate in Excel rather than showing frozen numbers.
Formulas, formats, filters
Number, currency, percentage and date formats. Sort and filter. Conditional formatting. Data validation. Find and replace. Freeze panes.
Comments on a cell
A comment anchors to a cell and moves with it — insert a row above and it follows. Someone with your link can read the sheet and comment, without being able to change a thing.
Pictures in the drive, not the file
Paste a photo and it goes into your drive with a reference in the sheet. A five-megabyte picture never makes a spreadsheet stop saving.
Export to Excel, CSV and PDF
A real .xlsx with live formulas. CSV for one sheet. PDF for the whole workbook.
Templates
A monthly budget, an invoice that totals, a timesheet. Real starting points with formulas checked cell by cell.
Version history
The same checkpoints and restore as FastWrite. Whole-workbook, never a single cell.
Not yet: charts, pivot tables, and importing an existing .xlsx.
