Tidyset

See it running

Cleans CSV, Excel and JSON deterministically: it proposes each fix with a visible diff, you approve it, and the accepted steps become a reusable recipe that re-runs on next month's export.

Website Direct edition

Pay once. Fully unlocked. Verified by Apple.

This website download is a separate direct-distribution build from the Mac App Store edition. It contains no StoreKit purchase flow or subscription screen: every feature is available after the one-time website purchase.

Apple notarized this exact disk image after an automated malware check. It is signed with the publisher's Developer ID and its notarization ticket is stapled to the download, so Gatekeeper can verify it even when your Mac is offline.

What it is

What Tidyset does

Cleans CSV, Excel and JSON deterministically: it proposes each fix with a visible diff, you approve it, and the accepted steps become a reusable recipe that re-runs on next month's export.

The important word is deterministic. Tidyset does not guess at your values with a model. It detects whitespace, inconsistent labels, missing values and type problems, proposes a fix, and shows the before-and-after diff for you to accept or reject.

Every accepted action becomes a step in a recipe. The recipe is simultaneously your undo history, your audit trail, and the thing you re-run when the same messy export lands next month.

How it does its job

Reviewable suggestions

Each proposed fix shows its diff and its impact before it applies.

Fuzzy clustering

Groups 'NYC', 'New York City' and 'new york' so they can be normalised in one action.

Recipes as history

The applied steps are the undo stack and the replayable pipeline at once.

What it doesn't do

It will not infer missing data. It makes gaps visible instead of filling them with a plausible guess.

Common questions

What is Tidyset?

A focused Mac data-cleaning workspace: reviewable fixes for whitespace, labels and missing values, column profiling with histograms, fuzzy clustering, formulas and global find & replace - and every action becomes a reversible, reusable recipe. Fully offline.

Who is Tidyset for?

Tidyset is for Mac users looking for data tools. Cleans CSV, Excel and JSON with reviewable diffs - approved fixes become a recipe you can re-run.

Can I check a cleaning change before accepting it?

Yes. Tidyset proposes changes and shows a before-and-after difference. Accepted actions become recipe steps that can be reviewed, undone and reused on a later export.

Does Tidyset need an AI model to clean a spreadsheet?

Its core cleaning workflow is deterministic. It detects issues such as whitespace, inconsistent labels, missing values and type problems without asking a model to guess replacement values.

Which Macs can run Tidyset?

Tidyset requires macOS 14.4 or later. Supported architecture: Apple silicon and Intel. Check About This Mac before purchasing.
