Create SN-000001, ASSET-1001, equipment tags, and warranty lists without dragging formulas through a spreadsheet.
Build clean serial number lists for spreadsheet workflows

Asset-friendly prefixes
Use SN, SERIAL, ASSET, EQP, or a short department code before the number.
Sorted padded numbers
Create SN-000001 style labels that keep the same width and sort correctly.
CSV-ready output
Copy Excel formulas, paste fixed values, or download CSV/TXT for import sheets.
