Data cleaning and preparation apps for Mac

Data cleaning, training-data preparation and dashboard design are separate jobs. Choose the workspace that matches your input and check what its output represents before sharing it.

How to choose

Tidyset provides reviewable cleaning steps for CSV, Excel and JSON. Alembic prepares material for training and retrieval workflows. Keep an unchanged source copy so each transformation can be checked.

Dash Weaver is a dashboard-design studio with clearly labelled sample data. Its sample charts are useful for layout decisions; they are not live business metrics. Check the product page for the supported source and export boundaries.

Capabilities and limits

Alembic

Turns messy source material into a training-grade dataset: cleaning, deduplication, formatting and export to the shapes fine-tuning tools actually expect, with every step reversible.

Consider before buying: It cannot make a small or biased corpus representative. It makes what you have clean and legible.

Tidyset

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.

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

Dash Weaver

A local dashboard design and export studio for Mac with four professional presets, 24 sample-source blueprints, responsive editing, eight visualization types and five local report formats.

Consider before buying: Dash Weaver is a local design, rehearsal and export studio using deterministic bundled sample data. It does not authenticate with providers, connect to live APIs, databases, spreadsheets, webhooks or files, ingest production account data, evaluate thresholds, deliver notifications, sync in the background, provide cloud storage or support team collaboration. Names associated with its 24 source blueprints identify sample schemas only and must not be read as active integrations or provider endorsements. Dashboard movements and story rehearsals do not establish causality, compare external benchmarks, monitor real systems or produce decision-ready business recommendations; replace the sample values and validate the methodology in an appropriate production system before acting. Alert rules and destinations are drafts, not automation. Local profiles require explicit .dashw export for portability, and no cloud-save or concurrent-workspace guarantee is made.
