Exports & imports

Every format NetCalc Pro reads or writes, and when to use which one.

Core formats

Open the Export menu (top right of the subnet table) to pick a format. Most formats also round-trip through the Import button next to it.

  • JSON — the canonical format. Holds the full subnet tree, every label / notes / VLAN / AZ, plus the parent network, mask, and provider. Re-import this file to restore the exact workspace. A separate all workspaces option bundles every open workspace into one JSON file.
  • CSV — flat table: cidr, label, notes, vlan, az, hosts. Opens in any spreadsheet.
  • YAML — same shape as JSON, human-readable.
  • Markdown — documentation paste. A rendered tree plus a per-subnet table.
  • Print / PDF — opens your browser's print dialog; pick "Save as PDF" there.
  • SVG — topology view as a vector image.

Infrastructure as Code — Terraform

The Infrastructure as Code… entry opens a modal with two choices:

  • Cloud — AWS, Azure, GCP, Huawei Cloud, Alibaba Cloud, Oracle Cloud, IBM Cloud.
  • Target — one resource per subnet, or a single aggregate VPC resource that nests every subnet.

Output is Terraform HCL (.tf) only. CloudFormation, Pulumi, and Ansible exports were removed — Terraform is the one IaC format we commit to supporting across every provider, and users who need other tooling can translate from the HCL output.

Re-exporting the same plan produces the same bytes, so CI diffs stay clean.

IPAM paste-import

The top-level Import button handles two IPAM formats as paste-in content. Format detection is automatic — paste the text and the parser picks up columns versus keys.

  • Infoblox CSV — columns: network, netmask, label, notes, vlan. The netmask column accepts either the dotted form 255.255.255.0 or a full CIDR like 10.0.0.0/24.
  • NetBox YAML — keys: prefix, description or name, comments or comment, vlan. The VLAN field accepts a plain number or a NetBox-style object (vlan: { id: 101, name: vl-dev }); the first number in the field is used.

There is no dedicated IPAM tool modal. One Import button covers JSON snapshots, all-workspaces bundles, Infoblox CSV, and NetBox YAML.

Share link

Press the Share button in the sidebar footer to copy a URL of the form ?state=…. The link encodes your entire workspace — tree, labels, VLANs, provider — and opening it in any browser restores the exact plan. No sign-up, no server round-trip.

For multi-workspace fleets (like the Hybrid and Enterprise examples) the Load buttons use a short ?bundle_url=/examples/<fleet>.json form that fetches the bundle JSON at runtime, so the URLs stay under the browser's length limit regardless of fleet size.
