Fritz is a stand-alone Java application that provides spreadsheet analysis, visualization, and evaluation. Fritz computes advanced structures such as:
- Partitioned formula groups,
- Reference-based groups,
- Computation blocks, and
Furthermore, Fritz can be used to check if a spreadsheet contains smells. Fritz detects the following smells:
- Inter-worksheet smells (e.g., Feature Envy),
- Intra-worksheet smells (e.g., Long Calculation Chain),
- Input smells (e.g., Pattern Finder), and
- Structural smells (e.g., Overburdened Worksheet).
The calculated smell metrics can be displayed in the GUI or exported to a CSV file.
Version 1.0 of Fritz can be download here.
The tool was tested on an x64 Windows 10 machine, using JRE 1.8.0_121-b13.
Fritz can be used as command-line tool. Start it by the command
java -jar fritz.jar
We provide multiple command-line options. For an extensive list, start Fritz with the command
java -jar fritz.jar -help
Fritz also provides a graphical user-interface. This is the default start option.
When starting Fritz with GUI, the main application window appears.
The following menus and underlying operations are available:
- Open: select a spreadsheet file to open via a file chooser.
- Exit: ends the application
- Indication Options Window: toggles the related GUI window
- Context Information Window: toggles the related GUI window
- Value View: toggles between formula- and value view for the display of formulas
- R1C1 View: toggles between R1C1 and A1 style for the display of formulas
- Preprocess Corpus: toggles the related GUI window
- Start Corpus Evaluation: toggles the related GUI window
Fritz provides different application windows to control visualization and initiate advanced operations:
The main application window serves as visualizer for an opened spreadsheet file. Worksheets of the spreadsheet are displayed in separate windows.
Fritz provides a number of metric- and relation-indication options.
- Background Indications highlight specific cells in the main application window by applying background colors.
- Mouse-over Indications enable interactive coloring of cells in the main window based on a chosen relation
- Tool-Tip indications add specific tool-tips to cells in the main application window
- Indication Presets apply predefined sets of background, mouse-over, and tool-tip indications.
In this window, Fritz provides additional information and a number of calculated metrics for entities (cell, worksheet) related to the currently selected cell in the main application window.
