How to check the repeated entry in excel

Answer 1

To check for repeated entries in Excel, use conditional formatting to highlight duplicates, the COUNTIF function to count occurrences, or the remove duplicates feature to delete duplicates.

Step-by-step explanation:

To check for repeated entries in Excel, you can use conditional formatting, the COUNTIF function, or remove duplicates feature. Here are the steps for each method:

1. Conditional Formatting: Select the range where you suspect duplicates. Go to the 'Home' tab, click on 'Conditional Formatting', choose 'Highlight Cells Rules', and then 'Duplicate Values'. You can then choose a format for highlighting duplicates.
2. COUNTIF Function: In a new column adjacent to the data, use the formula =COUNTIF(range, cell)>1 to highlight entries that appear more than once. If the result is greater than 1, the entry is a duplicate.
3. Remove Duplicates: Select the range of cells, go to the 'Data' tab, and click on 'Remove Duplicates'. Excel will then delete any duplicate entries, leaving only unique records.

Each of these methods serves a different need: conditional formatting helps in highlighting duplicates without removing them, COUNTIF provides a count of how many times a value repeats, and Remove Duplicates quickly deletes any repeated entries.
