Tableau Prep 18.32

Tableau Prep by Tableau Software is a visual data preparation tool that makes it faster and easier to combine, clean, and reshape data for analysis—especially in Tableau. It pairs an intuitive, step-by-step flow canvas with immediate, visual feedback, so you can understand your data, fix quality issues, and produce trusted outputs without writing code.

Key capabilities:

• Visual flow authoring: Build repeatable prep workflows with interactive steps and live results.
• Smart cleaning: Identify outliers and nulls, change data types, split fields, pivot and aggregate, and use Group and Replace to standardize similar values.
• Blend and reshape: Join and union tables from multiple sources, including databases, spreadsheets, and cloud data.
• Data profiling: See distributions and summaries for every field to spot issues early.
• Calculations consistent with Tableau: Create calculated fields using familiar expressions.
• Scalable connectors and outputs: Connect to popular data platforms (e.g., SQL Server, Snowflake, BigQuery, Redshift, Oracle), files (CSV, Excel), and publish outputs to Tableau Server/Cloud, write back to databases, or export to .hyper and .csv.
• Automation and governance: Author flows in Tableau Prep Builder (desktop) and schedule, monitor, and manage them with Tableau Prep Conductor in Tableau Server or Tableau Cloud, with lineage and governance available when licensed.

Who it’s for:

• Data analysts and business users who need self-service tools to prepare messy or disparate data quickly.
• BI and data teams looking to standardize and automate data preparation for repeatable, governed analytics pipelines.

Availability and licensing:

• Tableau Prep Builder runs on Windows and macOS and is typically included with a Tableau Creator license.
• Tableau Prep Conductor requires Tableau Server or Tableau Cloud with the appropriate Data Management licensing to schedule and manage flows at scale.

With Tableau Prep, teams reduce the time spent wrangling data and accelerate the path from raw information to reliable, analysis-ready datasets.
