Playground features

Try TrueCalc's interactive spreadsheet — editing cells, filling formulas, copy and paste, undo/redo, and formatting — live in the browser.

The playground is a full interactive spreadsheet running on TrueCalc. Each page in this section explains one editing feature, then lets you try it live in an embedded grid — no install, no sign-up.

Edit a cell — type a value or a formula.
Fill a formula across cells — extend a formula; references adjust.
Copy, cut, and paste — move and duplicate cells.
Undo and redo edits — step backward and forward.
Bold a cell — toggle presentation formatting.

Every grid you see below is the live playground, seeded with a starting layout so you can reproduce the described behavior yourself.
