DTM Data Generator for Excel is a specialized utility developed by DTM soft to help developers, test engineers, and QA teams automatically create large, realistic test spreadsheets in bulk. Instead of wasting hours manually typing out mock data, it generates thousands of realistic rows in seconds.
The utility functions as both a standalone application and an Excel add-in (via a DataGeneratorExcel.xll file). Key Features
Built-in Value Library: It provides more than two dozen built-in generators for mock identifiers like URLs, physical addresses, e-mails, IP addresses, phone numbers, and postal codes. It also includes predefined lists for structural data like countries, currencies, cities, and streets.
Intelligent Data Sources: You can use external data to populate your sheets. It supports pulling dummy data from text/CSV files, other Excel spreadsheets, XML files, databases, or desktop formats like Microsoft Access and DBF.
Web Data & Regex Support: The software supports using regular expressions to match specific string patterns, as well as functions like \(WebFile</code> to pull dummy content directly from online web services.</p> <p><strong>Complex Data Rules</strong>: It allows you to specify column-to-column dependencies (e.g., Column C must equal Column A + Column B) and can even reference values from previous lines to make sequential business data look realistic.</p> <p><strong>Structure Management Tools</strong>: To easily configure your spreadsheet template, it offers native structure operations like column moving, duplicating, copying, merging, and clipboard sharing.</p> <p><strong>Dynamic File Naming</strong>: It includes macros like <code>\)DATE\(</code> and <code>\)TIME$ to automatically customize output filenames, preventing you from accidentally overwriting previous test runs. Why Use It for Software Testing?
Massive Scale: Creating thousands of realistic test rows manually is too expensive and slow. This tool populates data sets instantly to test application thresholds.
Robust QA Testing: By implementing variable data shapes, custom regular expressions, and random string functions, you can stress-test how your system handles edge cases, empty fields, or specific length constraints.
Data Security: Instead of risking privacy violations by using real customer data in your testing or staging environments, it allows you to build completely fictional, synthetic data sets that behave exactly like the real thing.
A demo version of the software is available for evaluation and can be downloaded directly from the official DTM Database Tools Excel Generator Page. If you’d like, let me know:
What specific type of data you need to generate (e.g., financial data, user profiles)?
Whether you are testing Excel formulas or feeding these sheets into an external software system?
If you need an alternative that handles other formats like JSON or SQL?
