Frequently Asked Questions: How to Clean Up Data in Google Sheets
What is the best way to remove duplicates in Google Sheets?
To remove duplicates in Google Sheets, you can use the “Remove duplicates” feature. Select the range of cells that contains the data you want to clean up, go to the “Data” menu, and click on “Remove duplicates”. This will remove all duplicate rows based on the values in the selected columns. You can also use the “UNIQUE” function to remove duplicates and return a list of unique values.
How do I trim excess spaces in Google Sheets?
To trim excess spaces in Google Sheets, you can use the “TRIM” function. This function removes any leading or trailing spaces from a text string. For example, if you have a cell with the value ” Hello World “, you can use the formula “=TRIM(A1)” to remove the excess spaces and return the value “Hello World”.
What is the best way to standardize date formats in Google Sheets?
To standardize date formats in Google Sheets, you can use the “TEXT” function. This function converts a date value to a text string in a specified format. For example, if you have a column of dates in the format “mm/dd/yyyy”, but you want to standardize them to “yyyy-mm-dd”, you can use the formula “=TEXT(A1,”yyyy-mm-dd”)”. This will convert the date value to the desired format.
How do I handle inconsistent data entry in Google Sheets?
To handle inconsistent data entry in Google Sheets, you can use data validation rules to restrict the types of values that can be entered into a cell. For example, you can set up a rule to only allow dates in a specific format, or to only allow values from a specific list. You can also use conditional formatting to highlight cells that contain inconsistent data, making it easier to identify and correct errors.
What is the best way to split text into separate columns in Google Sheets?
To split text into separate columns in Google Sheets, you can use the “SPLIT” function. This function splits a text string into multiple columns based on a specified delimiter. For example, if you have a column of values in the format “First Name Last Name”, you can use the formula “=SPLIT(A1,” “) to split the values into two separate columns, one for the first name and one for the last name.
