XLSX
Estimate and cable schedule — editable in Excel: prices, quantities, totals.
Import
Floor plan images (PNG/JPEG) for redrawing, DXF for importing walls, JSON for full projects.
Why it matters
No vendor lock-in: the documents are in open formats — the customer and the inspector open them anywhere.
