Network Sketcher generates network configuration diagrams in PowerPoint and manages configuration information in Excel. Additionally, exporting a AI context can be used to generate config files using LLM.
- Automatic generation of each configuration document by metadatization of network configuration information
- Automated synchronization between documents
- Minimize maintenance and training load by automatic generation of common formats
- Facilitate automatic analysis, AI utilization, and inter-system collaboration by metadatization of configuration information.
- Template support for equipment configuration

- Ver 2.6.1
Network Sketcher Ver 2.6.1 supported the creation of a network configuration with LLM from scratch
- Ver 2.6.0
Although Network Sketcher now supports multiple formats, it is not intended to replace the main drawing tool, but rather aims for mutually beneficial development.
- IPv4 only. IPv6 is not supported.
- A DEVICE file contains multiple sheets, but only one sheet should be updated at a time. Simultaneous synchronization of multiple sheet updates is not supported.
- Do not use Network Skecher on master files in your One Drive folder.
- Deleting Layer 1 links using the GUI cannot identify individual interfaces and will delete more Layer 2 data than intended. Use the CLI command (delete l1_link) to delete Layer 1 links.
- Network Sketcher supports cross-platform. Works with Windows, Mac OS, and Linux.
- MAC OS may not display well in Dark mode.
- Python ver 3.x
- Software that can edit .pptx and .xlsx files
- Microsoft Powerpoint and Excel are the best
- Google Slides and Spreadsheets import/export functionality is available. Excel functions display will show an error, but it works fine.
- Libre Office and Softmaker office cannot be used.
