A clear path from files to finished.

Start with the outcome you need. Datally takes care of connecting the steps.

  1. 01

    Give Datally your files

    Add CSV or Excel files. Include a target example if you have one. Otherwise, Datally proposes a structure from your sources.

  2. 02

    Follow the progress

    Datally coordinates the analysis, column matching, value translation, and checks. See what is happening and why.

  3. 03

    Review your result

    Resolve uncertain choices, inspect the output, and download your dataset. The preparation is saved for future runs.

Automation you can follow

See the work. Understand the decisions.

Preparation comes with a record of what happened, where Datally is confident, and what still needs a closer look.

Explore the capabilities

A target, even without a template

Datally proposes an output structure from the source files and asks before combining similar column names.

Questions with context

Review the source values and the proposed decision. Accept it or make a correction before continuing.

A result you can inspect

Preview rows, review validation findings, and trace the output back to the preparation that produced it.

Your workspace. Your choice.

Keep the work on your machine.

The desktop app processes files locally. Use local models for AI assistance, or continue with deterministic matching and review when AI is unavailable. Cloud AI is optional.

How Datally handles your data

Local file processing

Your desktop project and its output stay on your device.

AI that fits your setup

Automatic uses compatible, available models. Local models need an initial download; licensing uses an internet connection.

Advanced when you need it

Open the workbench to inspect dictionaries, mappings, translations, and rules in detail.
