Is this faster than setting up a Power Query append to merge Excel files?

For a one-time or infrequent merge, yes — significantly. Power Query requires configuring a data source connection, defining the append query, and refreshing manually or via schedule. Deliteful requires uploading files and clicking merge.

Will this break if new columns are added to one of the source files?

No. The tool uses column-union logic, so any new column is automatically included in the output. Rows from files without that column get an empty cell. There is no fixed schema to maintain.

Can I use the merged output as input for another automation step?

Yes. The output is a clean .xlsx with raw values and a flat structure — no formulas, no merged cells — which is reliable input for Python (pandas/openpyxl), Power Automate, or any ETL tool.

Does the tool support .xls files from older Excel versions?

Yes. Both .xlsx and legacy .xls files are accepted as input.

What's the column ordering logic in the merged output?

Columns appear in the order they are first encountered across input files. The first uploaded file's columns come first, followed by any new columns introduced by subsequent files.

Merge Multiple Excel Files Into One Sheet Without VBA or Power Query

Setting up a Power Query append or writing a VBA macro to consolidate Excel files is overkill for a task that needs to happen once a month — and both break when column structures change. Deliteful's Excel Merge tool handles multi-file consolidation without any setup: upload, merge, download.

Spreadsheet automation workflows frequently hit the same bottleneck: merging Excel files from different sources requires either maintaining a fragile VBA script, configuring a Power Query append (which breaks when a new column appears), or doing it manually. For teams without a dedicated Excel developer, each of these options has a maintenance cost that exceeds the value of the automation. A web-based merge tool with column-union logic sidesteps this entirely.

Deliteful's approach is deliberately simple: first worksheet from each file, all rows combined, all columns unioned, empty cells where data is absent. No template to maintain, no query to refresh, no macro to debug. The output is a flat .xlsx with raw values only — consistent input for any downstream automation, whether that's a Python script, a BI connector, or another Excel workbook.
