No-signup preview

Turn a messy circuit spreadsheet into a traceable handoff record.

Upload a .csv/.tsv/.xlsx/.xlsm file or paste up to 20 rows, map rough column headers, preview normalized records, trace A-to-Z, and generate one LOA/CFA-style handoff preview. Paid workspaces keep the data, reminders, audit history, capacity warnings, and team workflows running.

Sandbox boundary: everything runs in your browser. Uploaded files are read locally with no network call. Nothing is saved, stored, synced, sent to a server, or written to production.

What this proves

  • Flexible headers can be mapped into controlled circuit records.
  • A-End and Z-End become a visual path, not just cells in Excel.
  • Renewal, MRC, Power/RPP, and provider fields become operations signals.
  • One LOA/CFA preview shows the document workflow without giving away the paid engine.
Step 01

Upload or paste CSV / Excel rows

Upload a .csv/.tsv/.xlsx/.xlsm file, drag one onto the box, or paste from Excel/Sheets. The sandbox auto-maps the first 20 data rows for preview; nothing is uploaded or saved.

Step 02

Column mapping

Auto-mapping is intentionally lightweight. The authenticated paid importer handles larger batches and real carrier mess.

Step 03

Normalized records

Step 04
A-to-Z path trace
Select a row
Select a normalized row to see its customer cabinet to provider demarc path.
Step 05

One LOA/CFA preview

This preview is capped at one generated handoff. Paid workspaces save versioned PDFs to the document library with signature status and audit history.

This disappears when you close the tab.
