It’s common to input data in different Excel spreadsheets by different people and sum them later. But as you know, if you copy a column of data and copy them into another table, the existing data will be overwritten. Is there a way to **sum the data across multiple Excel tables in different sheets**?

## How to Sum Two Excel Tables

If there are only 2 tables you want to sum, using ** Paste Special** should be easier than using Excel functions.

1. First, select the cells you want to sum in Table 1 and press **[Ctrl+C] **to copy them.

2. Then switch to Table 2 (no matter in the same sheet or anther sheet), and select the same range of cells as in Table 1.

3. Next, right-click the selected area, click ** Paste Special…** directly under

**.**

*Paste Options*Or click the arrow beside ** Paste Special…** to expand the menu.

Then click ** Paste Special… **here.

4. When the ** Paste Special** pop out, select Add in the

**section. Click**

*Operation***to implement the pasting.**

*OK*5. Then the selected data in Table 1 will be added to the same range of data in Table 2. And the calculation result of summation will show immediately without any formula.

## How to Sum More than Two Spreadsheets

With more than two tables in different sheets, ** Paste Special** can hardly help you. You can use

**SUM function**to achieve the same goal.

Assuming there are 3 tables to sum – Table 1, Table 2 and Table 3.

1. If you want to calculate the summation in Table 3, then create a new column in it.

2. Enter the formula in C2: **=SUM(‘Table 1′!B2,’Table 2′!B2,’Table 3’!B2)**

The content inside **”** refers to the sheet name; the content after **!** refers to the data you want to sum in this row. So this formula aims at calculating the summation of B2 in Table 1, Table 2 and Table 3.

3. Press **[Enter]** to work it out, and drag your mouse to use Fill Handle applying the same formula to the cells below.

4. Now all the values of column B in the 3 tables have been summed up. You can use this formula to sum even more tables.
