We design the tools the Qlik ecosystem is built with.

Q-Explorator is a Windows desktop application: it installs on your machine and works directly with your QVD, CSV, Excel, and Parquet files. Q-Expert is a SaaS product: a visual canvas you access from the browser, by subscription, with nothing to install.

Q-Explorator explores and audits your QVD, CSV, Excel and Parquet files before you write a single line of code. Q-Expert visually builds the Qlik transformation script. They're complementary — one helps you understand the data, the other transforms it.

Yes. The Free tier lets you explore up to 10,000 rows per file at no cost. Premium plans (starting at 1 month) remove that limit and unlock Calculated Columns, the Associative Filter Panel, Report View, Export, Save Workspace, and language/theme switching.

Q-Expert is currently in its testing phase. You can explore all of its features on this same page; access to the app will open up as soon as it's ready to launch.

Yes. Completing one full paid year of Q-Expert earns a Q-Explorator license with no row limit, permanently — this applies to Q-Expert subscriptions started from here forward.

We don't sell your data or use it for advertising. You can see the full detail in our Privacy Policy.

Yes. Reverse Engineering takes an existing .qvs script and rebuilds its canvas automatically, node by node. Anything it can't resolve with certainty is kept as a Raw Script block instead of being guessed at, so nothing from the original is lost or altered.

QVD, Excel, CSV and TXT files, and sources already materialized in the Transformation layer. It deliberately doesn't connect directly to databases (SQL/ODBC) — that's a step earlier in the data architecture, handled before Q-Expert.

RAW is the Extraction stage of the model, one of three: RAW, TXF, BUS. It's data exactly as it arrives from the source — QVD, Excel, CSV, or generated with Autogenerate — with no transformation applied yet; Q-Expert starts one step later, at TXF. This isn't the same thing as a Raw Script block, which only shows up in Reverse Engineering — see the next question.

A Raw Script block has nothing to do with the RAW layer of the data model (RAW/TXF/BUS). It only shows up in Reverse Engineering: when it rebuilds a canvas from an existing .qvs script, anything it can't resolve with certainty is kept as a Raw Script block instead of being guessed at — the original code stays exactly as written, attached to the canvas, so nothing is lost or silently altered.

It's where the real work happens: JOIN, CROSSTABLE, ApplyMap, SK/CK keys, WHERE, GROUP BY, calculated expressions — each TXF resolves one piece of the model, in isolation. This is the layer Q-Expert is built for.

The final result, ready for the app's associative model — stored to QVD with STORE, and the only thing the BI team needs to consume.

Surrogate (SK) and composite (CK) keys. Mark a column as one and Q-Expert cascades the prefix, name resolution and QUALIFY automatically, instead of you writing that boilerplate by hand in every table.

Checkpoints are STORE / EXIT SCRIPT points with a global on/off switch, so you can enable or disable them all at once. The Script Splitter divides a long flow into several physical .qvs files, so the script stays manageable as it grows.

You switch between Dev, QA and Prod without touching the diagram — each profile keeps its own lib:// path mapping, and Deploy writes the .qvs straight to disk for whichever environment is active.

A tool for building Qlik expressions with a function search, nestable cards and a live preview, without leaving the column you're editing.

A Premium feature that lets you filter your data through guided navigation, simulating Qlik's green-white-gray associative model — click a value and watch the whole file filter itself instantly.

A Premium feature: name the column, write the expression, and Q-Explorator evaluates it against every row of the current file. The expression field expands into a full editor with the available column names as quick reference.

A Premium feature: a nested summary tree, with expandable detail, for building a real hierarchical report over the data you've loaded.

Search and mark data to filter the records of the current DataPage, show or hide columns, and save those defaults for the next load — marking works on the free tier, on the current 10,000-row DataPage; the Associative Filter Panel is the Premium, whole-file version of filtering.
