Deterministic network diagrams from structured Excel
Turn device, port, and link data into validated Excel workbooks and deterministic draw.io diagrams.
How it works
Device + port data → validated Excel workbook → deterministic draw.io output.
Define devices
Add network devices, assign tiers, and organize into logical pairs. Schema guides valid input.
Sign in to start →Generate workbook
Download a structured Excel template with port groups pre-populated from your device definitions.
See pricing →Map connections
Fill in actual cable connections in the Excel file. Define media types, speeds, port channels.
Read FAQ →Generate diagram
Upload the completed workbook and generate a deterministic diagram export for review and handoff.
Sign in to upload →What you get
Real network documentation workflow.
Template generated from your device definitions
Build a workbook with tiers, devices, and connection fields already organized for completion and review.
Repeatable diagrams for review, handoff, and standards work
The same validated input produces the same layout and labeling, making change review and documentation control easier.
Why deterministic matters
Predictable output is easier to review, edit, and standardize across teams.
Deterministic layouts
Same validated input, same output. Easier reviews and standards enforcement.
Validation-first workflow
Catch malformed device and connection data before it turns into diagram cleanup work.
Small-topology evaluation
Try the real workflow on topologies up to 8 devices and 3 tiers before moving to Plus.
Editable downstream output
Export to draw.io so the final diagram can still be reviewed, annotated, and handed off.
The process
Define devices → generate workbook → fill connections → validate → export diagram.
