No macros. No VBA. No manual entry. PV-COM sends the weight directly to the active Excel cell, advances to the next row and keeps capturing. Compatible with all versions from Excel 97 to Microsoft 365.
How it works
PV-COM acts as an invisible bridge between your scale and Excel. It does not modify Excel in any way — it simply sends the weight as if it were a keyboard.
Connect your scale to the PC via RS-232 or USB. PV-COM detects it automatically.
Open your spreadsheet and click on the cell where you want the first weight.
Place the object on the scale. PV-COM waits for the weight to stabilize.
The weight appears in the active cell and automatically advances to the next row.
How does PV-COM send the weight? PV-COM uses keyboard emulation: it "tells" Windows that a number is being typed, exactly as if an operator were entering it. That's why it works with any Excel version without requiring add-ins, special drivers or macros. The weight can include the unit (kg, g, lb) and you can configure whether Enter, Tab or no key is pressed at the end.
Excel-specific features
PV-COM has options designed to make working with Excel more efficient.
After each weighing, PV-COM can press Enter or Tab to automatically advance to the next row or column. Serial weighing without touching the keyboard.
Enter · Tab · PersonalizablePV-COM captures the weight only when the scale indicates it is stable. Prevents capturing weights in motion or transient values.
Filtro de estabilidadChoose how many decimals to send, whether to include the unit (kg, g, lb), and the decimal separator (period or comma) based on your Excel regional settings.
Decimales · Unidad · SeparadorIn addition to sending to the active cell, PV-COM can save weighings directly to an Excel or CSV file in the background, without Excel being open.
Excel · CSV · BackgroundConfigure PV-COM to send the date and time of each weighing to the adjacent column along with the weight. Complete automatic log.
Fecha · Hora · AutomáticoIn continuous mode, PV-COM captures the weight every X seconds or whenever it detects a new object on the scale. Ideal for production lines.

Compatibility
From legacy versions to the latest release. PV-COM does not require any special Excel features because it works at the operating system level, not inside Excel.
Requirement: Windows 10 or Windows 11 (32 or 64-bit). PV-COM does not work on macOS or Linux. Excel can be installed locally or in web mode (Microsoft 365 in browser) — in both cases PV-COM sends the weight to the active cell.
Frequently asked questions
Answers to the most common questions about the integration.
Technical guide
With PV-COM, connect the RS-232 scale to the PC serial port (or via USB-RS232 adapter), configure the baud rate and scale model in PV-COM, open Excel, click the cell and the weight appears automatically when weighing.
Manual weight entry generates transcription errors that can cost money in inventory and shipping. PV-COM eliminates manual entry by sending the weight directly from the scale to the Excel cell, completely removing human error.
To log many consecutive weighings in Excel, configure PV-COM in continuous mode with automatic cell advance. Each time the scale detects a stable weight, it sends it to the active cell and advances to the next row. No manual intervention between weighings.
One lifetime license. Remote installation included. 1-year support.
