In the Content header cell, click on the double pointed arrow. Select the columns that you want to combine. If you want to combine all columns, make sure (Select All Columns) is checked. Uncheck the ‘Use original column name as prefix' option.
- With Power Query, working with data dispersed across worksheets or even workbooks has become easier. One of the things where Power Query can save you a lot of time is when you have to merge tables with different sizes and columns based on a matching column. Below is a video where I show exactly how to merge tables in Excel using Power Query.
- In this Excel tutorial, I will show you different methods to compare two columns in Excel and look for matches or differences. There are multiple ways to do this in Excel and in this tutorial I will show you some of these (such as comparing using VLOOKUP formula or IF formula or Conditional formatting).
Introduction
One of the most commonly used pandas functions is read_excel
. This short article shows how youcan read in all the tabs in an Excel workbook and combine them into a single pandas dataframe usingone command.
For those of you that want the TLDR, here is the command:
Read on for an explanation of when to use this and how it works.
Excel Worksheets
For the purposes of this example, we assume that the Excel workbook is structured like this:
The process I will describe works when:
- The data is not duplicated across tabs (sheet1 is one full month and the subsequent sheets have only a single month's worth of data)
- The columns are all named the same
- You wish to read in all tabs and combine them
Understanding read_excel
The read_excel
function is a feature packed pandas function. For this specificcase, we can use the sheet_name
parameter to streamline the reading in of all the sheetsin our Excel file.
Most of the time, you will read in a specific sheet from an Excel file:
If you carefully look at the documentation, you may notice that if you use sheet_name=None
,you can read in all the sheets in the workbook at one time. Let's try it:
Pandas will read in all the sheets and return a collections.OrderedDict
object. For the purposesof the readability of this article, I'm defining the full url and passing it to read_excel
. In practice,you may decide to make this one command.
Let's inspect the resulting all_dfs
:
If you want to access a single sheet as a dataframe:
account number | name | sku | quantity | unit price | ext price | date | |
---|---|---|---|---|---|---|---|
0 | 412290 | Jerde-Hilpert | S2-77896 | 43 | 76.66 | 3296.38 | 2018-03-04 23:10:28 |
1 | 383080 | Will LLC | S1-93683 | 28 | 90.86 | 2544.08 | 2018-03-05 05:11:49 |
2 | 729833 | Koepp Ltd | S1-30248 | 13 | 44.84 | 582.92 | 2018-03-05 17:33:52 |
3 | 424914 | White-Trantow | S2-82423 | 38 | 50.93 | 1935.34 | 2018-03-05 21:40:10 |
4 | 672390 | Kuhn-Gusikowski | S1-50961 | 34 | 48.20 | 1638.80 | 2018-03-06 11:59:00 |
If we want to join all the individual dataframes into one single dataframe, use pd.concat:
In this case, we use ignore_index
since the automatically generated indicesof Sheet1
, Sheet2
, etc. are not meaningful.
If your data meets the structure outlined above, this one liner will return a singlepandas dataframe that combines the data in each Excel worksheet:
Summary
This trick can be useful in the right circumstances. It also illustrates how muchpower there is in a pandas command that 'just' reads in an Excel file. The full notebookis available on github if you would like to try it out for yourself.

Summary:
Does merging rows and columns in Excel seems a tough task for you to perform? Read this tutorial to learn different ways to merge rows and columns in Excel.
Microsoft Excel is a very useful application and can be used for performing various tasks. This is the reason Excel provides various useful functions to make the task easy for the users.
One of the most common tasks that everyone needs performing now and then is merging rows and columns.
But the problem is that performing this is not an easy task and Excel does not provide any tool to do this.
This is quite complicated as merging rows and columns in some cases causes data loss.
As while trying to combine two or more rows in the worksheet by making use of the Merge & Center button (Home tab > Alignment group), you will start getting the error message:
'The selection contains multiple data values. Merging into one cell will keep the upper-left most data only.'
And if you click OK, merged cells would contain just the value of the top-left cell and as a result, entire other data will be removed.
So this is what leads you to Panic situation!!!
To get rid of this, today in this article I am sharing different ways to easily merge rows and columns in excel without losing any data.
Below check out the fixes on how to merge rows in Excel or how to merge columns in Excel.

How To Merge Rows & Columns In Excel Without Losing Data?
There are different methods for combining row and columns text in Excel. Here check the ways one by one to merge data without losing it. First, check how to merge rows in Excel.
Part 1# How To Merge Rows in Excel
When it comes to merging the Excel rows there are two ways that allow you to merge rows data easily.
- Merge Excel rows using a formula
- Combine multiple rows using the Merge Cells add-in
1. How to Merge Multiple Rows using Excel Formulas
Excel provides various formulas that help you combine data from different rows. Possibly the easiest one is the CONCATENATE function. So here checks out some examples for concatenating numerous rows into one:
- Merge rows with spaces between data: For example =CONCATENATE(B1,' ',B2,' ',B3)
- Combine rows without any space between the values: For example =CONCATENATE(A1,A2,A3)
- Merge rows > separate the values with comma: For Example =CONCATENATE(A1,', ',A2,', ',A3)
Now check how the CONCATENATE formula works on the real data.
- On the sheet choose an empty cell and type the formula into it. Type the formula as per the data rows
- And copy the formula across entire other cells in the row.
- Now, simply you are having several data rows merged into one row.
2. How to Combine Rows in Excel using the Merge Cells Add-in
The Merge Cells add-in is used for merging various types of cells in Excel. This allows you to merges the individual cells and also combines data from entire rows or columns.
Please Note: You need to download a merge cell add-ins for third-party sites available online. Search in Google for add-ins.
Follow the given steps to combine two or more rows in your table:
- Choose rows you are looking to merge > click on the Merge Cells icon.
- Now the merge cells dialog window opens with a table or range selected already. And in the upper part of the window, you can see the three basic things:
- How you want to join cells– For combining rows of data > choose 'column by column'.
- How to separate merged values with – an array of standard separators is available to choose from > comma, space, semicolon, anda line break. So select the separator as per your desire.
- Where you need to place the merged cells > either the top cell or bottom cell.
- Now check the lower part of the Windows to check if you need any additional options:
- Clear the content of selected cells – Choose this if need data to remain in the merged cells only.
- Merge all areas in the selection – This option allows you to merge rows in two or more non-adjacent ranges.
- Skip empty cells and Wrap text – Well, these are self-explanatory.
- Lastly, Create a backup copy of the worksheet – This option is checked by default. It is just a precaution that keeps you on the safe side and prevents the risk of data loss.
- Click the Merge button > to check the result – possible the merged rows of data separated by line breaks.
So, these are the two ways that allow you to merge rows in Excel without any data loss. Now, check out the ways on how to combine two columns in Excel.
Part 2# How To Merge Columns In Excel
Here check out the 3 ways to merge data from several columns into one without using VBA macro.
- Merge two columns using formulas
- Combine columns data via NotePad
- The fastest way to join multiple columns
1. Merge Two Columns using Excel Formulas
1. Into your table > insert a new column > in the column header place the mouse pointer > right-click the mouse > select Insert from the context menu. Name the newly added columns for eg. – 'Full Name'
2. In the cell D2, write the formula: =CONCATENATE(B2,' ',C2). The B2 and C2 are the addresses of First Name and Last Name. And in the formula, the quotation marks '' is the separator that will be inserted between merged names any other symbol can be used as a separator e.g. a comma.
3. Just like this, join data from several cells into one by making use of any separator of your choice.
4. Simply, copy the formula to other cells of the Full Name column. If the First name or the Last name is deleted, then the corresponding data in the Full name Column will also be gone.
5. Next, try converting the formula to a value so that you can remove the unnecessary columns from the Excel worksheet. Choose entire cells with data in the merged column (choose the first cell in 'Full Name' Column > press Ctrl +Shift + Arrow Down)
6. Now copy the contents of the columns to clipboard > right click on the cell in the same column ('Full Name') > choose 'Paste Special' context menu > choose 'Values' radio button > click OK.
7. Now remove 'First Name' & 'Last Name' columns that are not required. Click the column B header > press and hold Ctrl > click column C header.
8. After that make a right-click on any selected columns > select Delete from the context menu.
9. This is it, now you have successfully merged the names from 2 columns into one.
2. Combine columns Data via Notepad
This is another way that allows you to merge several columns. Here you don't need any formulas. This is suitable for combining adjacent columns to make use of the same delimiter for all of them.
For Example: If looking for combining 2 columns with First Names and Last Names into one:
- Choose both columns you need to merge: Click B1 > press Shift + ArrrowRight for choosing C1 > then hit Ctrl + Shift + ArrowDown for choosing entire data cells with data in two columns.
- And copy data to clipboard > open Notepad > insert data from the clipboard to the Notepad
- Then copy tab character to clipboard > hit Tab right in Notepad > hit Ctrl + Shift + LeftArrow > press Ctrl + X.
- After that Replace Tab characters in Notepad with the separator, you require.
- Hit Ctrl + H for opening the 'Replace' dialog box > paste the Tab character from the clipboard in Find what field > type the separator Space, comma etc in 'Replace with' field. Hit the Replace All button > to close the dialog box press Cancel
- Now select the entire text in the Notepad and copy it to Clipboard.
- Then switch back to Excel worksheet (press Alt + Tab) > choose B1 cell and paste text from Clipboard to your table.
- And rename column B to 'Full Name' and remove the 'Last name' column.
So, this is the second way that allows you to merge columns in Excel without any data loss.
