Will columns stay aligned if my Excel files have different column orders?

Yes. The tool performs a union of all columns found across every input file. Columns are ordered by first appearance, and rows from files missing a column receive empty values in that column — no manual realignment needed.

Does the merge preserve formulas from my source files?

No. Cell formatting, styles, and formulas are not preserved — only raw data values are carried into the merged sheet. This is intentional to prevent broken formula references across files.

Can I merge more than two files at once?

Yes. You can upload as many .xlsx or .xls files as needed in one batch. All first worksheets are combined into a single output file in the order files are uploaded.

Only the first sheet is used — what if my data is on a different tab?

The tool processes only the first worksheet of each file. If your data lives on a different tab, move or copy it to the first sheet before uploading.

Is this suitable for consolidating monthly P&L reports?

Yes — this is a primary use case. Upload January through December P&L files and receive one consolidated sheet with every row aligned by column header, ready for period-over-period analysis.

Merge Multiple Excel Files Into One Consolidated Sheet for Accounting

Every month-end close means hunting down Excel files from different departments and manually stitching them together — a process that wastes hours and introduces errors. Deliteful's Excel Merge tool combines the first worksheet from each file into a single aligned sheet automatically, so you spend time on analysis, not copy-paste.

Accountants routinely consolidate trial balances, departmental P&Ls, and cost center reports that each live in separate Excel files. Manually copying rows between workbooks risks misaligned columns, formula breaks, and version mismatches — especially under deadline pressure. A structured merge that unions all columns and fills gaps with empty cells eliminates these risks and produces a clean, auditable source file.

Deliteful processes each upload server-side and outputs a single 'Merged' worksheet containing every row from every input file's first sheet. Columns are aligned across all source files regardless of order, so a column that appears in only three of five files still lands in the right place. The original files are never modified, preserving your source records.
