What it does

Your existing files stay intact
Parts of a file the editors do not yet understand — pivot caches, themes, custom styles — are preserved byte for byte and written back on save. Opening a document in IronIngot does not quietly strip what it cannot display.
The PDF matches the screen
Export draws from the same display list the editor renders, so the exported document is what you were looking at, not a second implementation that drifts.
Recalculation in the right order
The spreadsheet works out which cells depend on which and recalculates along that graph, so a chain of formulas settles correctly in one pass.
Copy and paste works with Excel
Data copied out lands in Excel as data, and data copied in from Excel arrives as cells rather than a block of text.
PivotTables that recompute, not a frozen block
A PivotTable is stored as a definition rather than pasted values, so it reruns against the live cells and its fields and aggregate can be changed afterwards. Fields are chosen from four dropdowns rather than dragged into a field list. The limit worth knowing before you depend on it — a file saved here opens in Excel with the right numbers as ordinary cells, not as a pivot object Excel can re-pivot. Pivots that arrived in an Excel file are preserved as they were.
One engine, two faces
The desktop applications and the browser version share the same core, so a file behaves the same in both rather than the web version being a limited preview.
It exists to remove a per-seat fee
IronIngot was built so IronDrive could stop paying a per-user licence to a third party for in-browser editing. That cost saving is the whole reason it is worth writing.
