Migrate spreadsheet IP data without a risky cutover
Spreadsheets are a common starting point for IP address management, but they become harder to trust as networks grow.
LightMesh helps you migrate from Excel or CSV files into a shared IPAM workspace. Import your existing subnet and IP assignment data, validate records, and move gradually while your team builds confidence in a reliable source of truth.
Common pain points with spreadsheet IPAM
Teams outgrow shared .xlsx files quickly:
- Duplicate allocations when two admins update the same range
- No audit trail when someone changes a cell
- Version chaos from emailed attachments
- Manual reconciliation across DHCP, cloud, and spreadsheet data
Import your spreadsheet in minutes
LightMesh imports CSV, XLS, and XLSX files with column mapping — no rigid schema. Bring subnets, IP addresses, zones, devices, and custom fields from your existing workbook.
You do not need a perfect file on day one. Many teams import a baseline, then enrich with discovery and cloud sync over time.
Gradual migration, not a big bang
- Export your current spreadsheet (or start from our template).
- Import into LightMesh.
- Validate conflicts, gaps, and capacity.
- Run in parallel while the spreadsheet becomes read-only.
- Add cloud and DHCP discovery to fill gaps spreadsheets cannot see.
- Retire the spreadsheet when LightMesh becomes the trusted IPAM source of truth.
Why teams switch to LightMesh
- Visual subnet planning for capacity and overlap review
- Structured IPAM data instead of static spreadsheet rows
- Cloud and DHCP visibility when your environment grows
