About Merge Excel

Merge Excel files the way the job needs. Twelve monthly reports can become one workbook with twelve sheets, each copied with its formulas, formatting, merged cells and column widths. Or, when the files hold the same kind of data, like sales exports from different stores, all the rows can be stacked into a single sheet ready for a pivot table. XLSX, XLS, CSV and ODS files can be mixed.

When stacking, Line up columns by their names is on by default, so columns are matched by their header names instead of their places. A file with the columns in another order, or with a column more or less, still lines up: the result has the columns of all files together, in the order they first appear, and names match even when spaces, full-width letters or capitals differ. The header row is used only once, Drop repeated rows keeps a row that turns up in several files just once, and a column with each row's file name lets you tell the stores apart. Charts and pictures aren't copied across, and stacked rows hold values rather than formulas.

Why use Cubfile for this

  • Sheets copied as they are

    Formulas stay live, and fonts, fills, borders, number formats, merged cells, column widths and frozen panes come across.

  • Columns matched by name

    Exports whose columns come in another order, or with an extra or missing column, still stack under the right headings.

  • No repeated rows

    Drop repeated rows keeps a row that appears in several files only once, even with the file-name column added, and the result says how many were dropped.

  • Know where each row came from

    Add a column with the file name puts the source file in front of every stacked row, ready to filter.

FAQ

Merge Excel: questions and answers

Does Merge Excel keep my formulas?
In One workbook, a sheet per file mode, yes. Sheets are copied with live formulas and their formatting. In stacked mode you get the calculated values, which is what a combined data table needs. Drop repeated rows removes rows that are identical in every column, not counting the file-name column if you add one, and it works whether or not columns are lined up by name. Remove Duplicates in Excel finds repeats by the columns you choose, such as an email address.
What if my files have different columns?
They still stack. With Line up columns by their names on, each column is matched by its header, so a file with its columns in another order, or with an extra or a missing column, lines up with the rest. A column that only some files have is added, and rows from the other files stay empty in it. Headers match even when spaces, full-width letters or capitals differ, such as Order ID and order id.
Can I merge Excel files for free?
Yes. One merge counts as one task. Visitors get 2 tasks in total and free accounts 2 a day, with up to 20 files of 50 MB each, while VIP merges up to 50 files of 1 GB each with no daily limit.
What are the sheets called in the merged workbook?
Each sheet gets its file name, shortened if needed, plus its original sheet name, such as Jan-Sales and Feb-Sales, so sheets with the same name don't clash. To turn the combined workbook back into separate files, Split Excel cuts it by sheet.
Are my spreadsheets private?
Yes. Files go over HTTPS, the merge runs in an isolated process and everything is deleted after an hour. We never look at your data or use it to train AI.
