"Introduction to forms for newbies: Master the efficient deduplication techniques for duplicate data"

When processing table data, you sometimes encounter a large amount of duplicate data. If it takes a lot of time and energy to find and delete it manually, how can you quickly find and delete the duplicate data? Step 1: Select the table, click the drop-down menu of "Duplicates" under the "Data" tab, and click to set duplicate highlights. At this time, the duplicate data has been filled with color. Step 2: Select the "Delete Duplicates" button in the "Duplicates" drop-down menu again, select the product name in the pop-up "Delete Duplicates" dialog box, and click the "Delete Duplicates" button to delete it. So how to avoid repeated data entry? Step 1: Select the cell area where you want to prevent repeated data entry with the mouse. Taking this table as an example, select the product name column, click the drop-down menu of "Duplicates" under the "Data" tab, and select "Reject entry of duplicates". Step 2: After setting up, when you enter duplicate content in this column, a "Duplicate" warning box will pop up, but you can continue typing by double-clicking the Enter key. If you need to set it to prohibit the entry of duplicates, you need to click the "Validity" button under the "Data" tab. In the pop-up dialog box, select the style as prohibited on the error warning page. At this time, double-clicking the Enter key will not work. Enter any duplicates in this column. Finally, if you need to clear this setting, select "Clear Rejected Entry Restrictions" under "Duplicate Items".
