1. Data comparison
First, we need to find [Table comparison] on the homepage of the Beyond Compare file comparison tool button. After clicking this function, you can open the table comparison function panel.

Figure 2: Open the file
After quickly opening two spreadsheets, the Beyond Compare file comparison tool will display the entire contents of the two tables by default and use blank lines Or mark them in red to show the specific differences between the two documents. As you can see from the example below, the table on the right has one more row of data than the table on the left.

2. Display differences
When there is a lot of data in the table, we cannot quickly view all data differences. In this case, you can click the [Difference] button in the toolbar to let the Beyond Compare file comparison tool only display specific differences. As you can see from the example in the figure below, there are three differences between the two tables.

3. Copy data
After finding the specific difference points, we can handle these differences according to the actual situation point. For example, after we find the missing row of the data on the right, we can copy the data in the table on the left and paste it into the table file on the right (users cannot directly paste data in the Beyond Compare file comparison tool and need to paste the data in the original data file ). In this way, we can quickly repair erroneously lost data.
