Spreadsheet questions
Using this tool as an Excel workbook
Use the browser calculator for speed, then take the result into the spreadsheet workflow that fits your business.
Can I export the Wastewater & BOD Surcharge Estimator to Excel?
Yes. Enter your information, review the live result, and select Export to Excel. Batch Scale creates a branded .xlsx workbook with your inputs and the result shown by the tool.
What is included in the Wastewater & BOD Surcharge Excel Spreadsheet?
The workbook includes a Tool Result sheet, an Inputs sheet, the original calculator link, and the date generated. When a supported calculator has an Excel formula profile, its result cells remain connected to the editable input cells.
Can I use the spreadsheet in Google Sheets?
You can import the .xlsx workbook into Google Sheets. Because spreadsheet applications sometimes interpret formulas and formatting differently, confirm any important result after importing—especially before using it for pricing, safety, compliance, or production.
Is the Excel download free?
Yes. The calculator and workbook are free. The first Excel export on a device asks for your email and permission to receive occasional practical Batch Scale resources. Once captured, later tool exports on that device download directly.
