AI Data Quality for Alteryx: Our Tool Library for Reliable Data in the AI Era — and Why We Made It Free
1. The Data Quality Wall: What the Data Really Says 1. Why the traditional project Cycle no longer worksArtificial Intelligence has its own language. And it's evolving fast.
According to the joint MIT Technology Review Insights × Snowflake (2024) study, conducted with over 275 international business leaders, 78% of companies are not yet fully ready for generative AI. The report identifies three priority roadblocks: data governance, data security, and data quality.
This statistic is not surprising. What's more surprising is what it actually entails. In our daily practice with major French and European banks, data quality issues fall into five recurring categories:
• Deficient completeness: mandatory fields missing in 5 to 30% of records — often silently, without alert
• Format inconsistencies: same data coded differently depending on the source (dates, currencies, country codes, third-party names)
• Undetected duplicates: between 2 and 15% duplicates in customer/third-party repositories
• Unidentified outliers: outliers that contaminate statistical analyses and ML models
• Missing documentation: datasets without description, lineage, or clear ownership
An AI project launched on such a foundation is doomed to underperform, regardless of the model's quality. This is where the real battle lies: in upstream data reliability, not in downstream model engineering.
The “so what” for your organization
Before launching your next AI project, require your teams to conduct a 5-day Data Quality audit on the critical datasets involved. You'll find that 60 to 80% of the project's value depends on this audit — not on the choice of LLM or framework.
2. Our Approach: Alteryx as the Backbone of Data Quality 2. Our conviction: start with the business pain point, not the technology1. LLM (Large Language Model)
We could have built a standalone Python library. We could have deployed it on Snowflake, Databricks, or a native cloud platform. We chose Alteryx. Here's why.
Alteryx is already present in major banks. At several of our clients (including a French universal bank where 700+ Finance employees use Alteryx daily), the tool has become the analytical foundation for business teams. Adding Data Quality capabilities within Alteryx, rather than alongside it, means meeting users where they are — not imposing a new tool on them.
Alteryx is no-code. A management controller, risk manager, or compliance officer can use our add-ons without writing a single line of Python. This is an adoption challenge: the best Data Quality tools are useless if they remain confined to Data Engineers' closets.
Alteryx is already integrated into banking stacks. Native connectors to SQL Server, Oracle, Snowflake, Databricks, SharePoint, Power BI, Tableau. Our add-ons inherit this ecosystem with no additional integration cost.
The 'So What'
Do you already have Alteryx in your organization? Use it as the backbone of your Data Quality. Don't have it but use Excel/Power Query daily? The switch to Alteryx for industrialized Data Quality workflows is one of the best ROIs we've observed — often less than 6 months to recoup license costs.
3. Two Tool Families, One Unified Philosophy 3. A six-step method, not six months2. Embeddings
Our library combines two distinct yet complementary approaches.
On one hand, classic, deterministic Data Quality tools. They apply clear rules, produce reproducible results, and provide a precise audit trail. They are essential for regulatory compliance — an AnaCredit, FINREP/COREP, or Basel IV report does not tolerate uncertainty in controls.
On the other hand, generative AI tools, which are non-deterministic but flexible. They leverage large language models (Mistral, OpenAI, Claude, Gemini) to process what rules cannot: synonyms, spelling errors, heterogeneous formats, and free text.
The golden rule we apply with our clients : start with deterministic methods (fast, auditable, economical), then leverage generative AI only where it provides incremental value — without ever compromising sovereignty or governance.
This prioritization avoids two classic pitfalls: the all-AI approach (costly, unpredictable, difficult to audit) and the all-rules approach (rigid, unable to handle ambiguous cases).
4. A Sample of Our AI Data Quality Tools for Alteryx4. Prime AI Fast Development Kit: the engine that makes it possible3. RAG (Retrieval-Augmented Generation)
• AI Prompting — The Bridge to Generative AI
Queries an LLM model from Alteryx with configurable credentials. Compatible with ChatGPT, Claude, Mistral, Gemini, internal models.
Advanced capabilities: 1 model × N prompts (batch), N models × 1 prompt (comparison), N models × N prompts (full benchmark).
Pitfall to avoid : do not send personal data to an external LLM without verifying your GDPR / AI Act framework.
• AI Comment — Automated Contextual Enrichment
Automatically generates a contextual comment for each row in a dataset. Configurable tone (formal, concise, detailed). Optional knowledge base.
Use cases: sales summaries, management control comments, document annotations.
Pitfall to avoid : never deploy to production without human validation.
• Data Profiling — The Essential Starting Point
For each field in a dataset, it exposes a complete set of statistics — count, count_distinct_value, count_null_value, pct_missing, avg_value, min/max, percentiles (5, 25, 50, 75, 95). The first thing to do when a dataset enters your pipeline. In 2 minutes, you can see if a field is 40% empty, if numerical values have outliers, or if distributions match your expectations.
Pitfall to avoid : never neglect this step. We've seen projects proceed to dashboards, only to discover 3 months later that a critical field was 60% empty.
• Completeness Check — Automated Compliance
Checks that the completeness rate of each field exceeds a minimum threshold defined in a configuration file (e.g., 0.8 for 80%). Ideal for automated checks in a regulatory reporting chain. Configure precisely by field, entity, and period.
• Uniqueness Check — Uncovering Duplicates
Detects duplicates and calculates occurrences per value. Simple or composite key. Among 900,000 customers of a major French bank, it's not uncommon to find 15,000 to 30,000 duplicates.
Pitfall to avoid : starting with composite keys, not just a single email.
• Data Validation — Your Business Rules Applied Automatically
Validates each record against configurable rules (regex, min, max, allowed lists). Pass/fail result per rule. Banking example: "IBAN in ISO 13616 format", "positive amount", "product code in allowed list". Document rules in a shared file, not within the workflow.
• Fields Checks & Fields & Types Checks — Structural Compliance
Verify that the dataset's structure matches the expected data model and automatically convert types if necessary. Ideal before integrating an external source.
• Reference Validation — Reference Data Alignment
Checks that values comply with authorized reference lists (ISO country codes, status codes, internal reference data). Establishes an MDM framework without requiring a heavy MDM tool.
Pitfall to avoid : keeping your reference data outside the workflow (shared file, reference database, external API).
5. The Typical Pipeline: How to Integrate These Tools 5. What concretely changes for business4. Agentic AI / Agentic AI
Step 1 — Explore with Data Profiling. First, understand the structure and anomalies.
Step 2 — Check Structure with Completeness Check, Uniqueness Check, Fields Checks, Fields & Types Checks.
Step 3 — Business Validation with Data Validation (configurable rules) and Reference Validation (authorized repositories).
Step 4 — Enhance with AI with AI Prompting and AI Comment. Only where AI provides incremental value.
Step 5 — Report via Power BI or Tableau dashboards fed directly from Alteryx, with a complete audit trail.
Each step is independent and composable.

7. Why we chose to make these tools free 7. Beyond prototypes, a transformation roadmapAn expanding AI glossary
A legitimate question: if these tools required several months of development, why make them free?
First, because Data Quality is a collective challenge. The French-speaking Alteryx ecosystem is rich but fragmented. Each team individually solves the same problems. Pooling robust tools helps everyone progress — including our competitors. We embrace that.
Next, because these tools are a gateway. A CDO who downloads the library, installs it, tests it, and discovers it works — starts to get to know us. When they have a real Data Quality transformation project, they will think of us.
Finally, because our business is not selling tools. Our business is consulting, managed services, and training. The tools are one of the supports for our expertise — not our main product.
The 'so what'
If you are an Alteryx user in banking, insurance, or a large enterprise: download the pack, test it on one or two internal use cases, and see for yourself. No commitment, no cost. If it works for you, let's talk.
In conclusion, data quality is not a control issue. It's a speed issue.
Reliable data allows an AI project to launch in 3 months instead of 18. It enables rapid iteration, testing multiple approaches, and scaling. Conversely, questionable data slows everything down — every decision becomes a debate, every anomaly an investigation, every deliverable a compromise.
Our AI Data Quality tools for Alteryx are designed to make this quality accessible, industrial, and sustainable — without extra effort for teams, without vendor lock-in, and without compromising sovereignty.
They are free. They are proven in demanding banking environments. They are designed to be understood and used by business teams — not just by Data Engineers.
All that's left is to try them.
