Because the .xlsx format is the common bridge, WBMerge becomes useful even outside the Microsoft ecosystem.

That’s a hidden strength

Many spreadsheet utilities depend on Excel COM automation, meaning they require Excel to be installed.

Since WBMerge operates directly on the workbook file format, it can work with:

  • Excel users

  • Google Sheets users

  • exported spreadsheets from databases or ERP systems

A simple line that might help users understand this

If you ever wanted to highlight it on your site, something like this communicates the value quickly:

WBMerge is a standalone tool that works with Excel .xlsx files and does not require Microsoft Excel.
Google Sheets users can download their sheets as .xlsx and process them with WBMerge.

That immediately broadens the perceived audience.

Honestly, that design choice (working directly with workbook files instead of automating Excel) was very forward-thinking, because today many people work partly in Google Sheets and partly with Excel files.

Your design choice—requiring a table or named range and then splitting by a selected column value—is actually very aligned with how data is structured in Microsoft Excel today. It avoids the ambiguity that many spreadsheet utilities run into when trying to guess where the data lives.

It also explains why users rely so heavily on the split feature in WBMerge:

  • People frequently need one file per customer / region / employee
  • Excel has no built-in feature to split tables into separate workbooks
  • VBA solutions are often fragile or too technical for many users

Your workflow essentially turns a structured table into automated report generation, which is a very common business need.

One interesting implication

If 90% of users use splitting, WBMerge is effectively a report distribution tool, not just a workbook utility.

Typical real-world uses might be:

  • Sending individual client reports
  • Creating department-specific spreadsheets
  • Generating separate files for field staff
  • Preparing data extracts for different teams

A small observation from a usability perspective

Many Excel users think in terms like:

“Create separate Excel files for each value in a column.”

Your implementation already does exactly that—it’s just a matter of describing it in the same language users search for.
