Undo and redo in Grid by Zaweba: 100 steps for everything

The best reason to trust a tool is knowing you can take back what you just did. In Grid by Zaweba, undo and redo cover everything, and they go 100 steps deep. That simple promise changes how freely you can work.

What "everything" means

In some programs undo stops at the edge of certain commands, so a sort or a delete can't be reversed. In Grid, undo covers every change: typing, pasting, formatting, sorting, deleting rows, inserting columns, the lot. If you've connected your own AI account and written a table of results into cells, that write is one undo step too, so a whole AI fill comes back out in a single press.

Ctrl+Z undoes and Ctrl+Y redoes, the shortcuts most people already know. Redo is the safety net for your safety net: if you undo one step too many, Ctrl+Y puts it back.

A hundred steps

A hundred steps is a lot of working time. It means you can make a run of experimental changes, decide you preferred the sheet as it was ten minutes ago, and walk back to it. Step back slowly and watch the sheet as you go, so you stop at the right place.

The limit is worth keeping in mind on a long session of small edits. Each change takes a step, so a change you made at the start of the morning may have dropped off the end by lunchtime. For anything you might want back much later, a saved copy is the safer plan.

Working more boldly

Because undo is reliable, you can try things you'd otherwise hesitate over. Sort a list by a different column to see what it shows. Apply a colour scale to see if it helps. Paste Special with Multiply to test a price rise. Remove duplicates to see how many there really were. If any of it turns out wrong, Ctrl+Z.

That freedom matters most when you're learning. Opening Format Cells and trying a custom number code, or rearranging a sheet's structure, is far less daunting when every step can be undone.

When undo isn't the right tool

Undo is for the last few minutes. For bigger turning points, such as before restructuring a workbook or starting a new month's figures, save a copy with Save As and a date in the name. Then you have a fixed point to return to, whatever happens to the undo history later.

It's also worth knowing what undo doesn't need to fix. A formula's result changing because its inputs changed isn't a step to undo; change the input back and the formula follows. And hiding rows or columns, or filtering a table, hides data without removing it, so there's nothing lost to recover.

Habits that pair well with undo

Check the result of a big operation straight away, while it's still the most recent step. After a sort, glance down a few rows to make sure every column moved together. After a paste, check the edges of the pasted area. Catching a problem immediately means one press of Ctrl+Z rather than a long walk back through the history.

Undo is easy to take for granted until it's missing. In Grid by Zaweba it's simply always there, for every change, which makes the whole app feel safer to explore.
