Formula Generator - UNIQUE function
The UNIQUE function is used to return unique rows or values from a given range. It discards any duplicates and returns the unique entries in the order in which they first appear in the source range. The function takes three arguments: 'range' specifies the range of cells to evaluate, 'by_column' is an optional argument that determines whether the uniqueness is evaluated by column (TRUE) or by row (FALSE), and 'exactly_once' is an optional argument that specifies whether to include only values that appear exactly once (TRUE) or all unique values (FALSE).
How to generate an UNIQUE formula using AI.
To obtain the UNIQUE formula in Excel, you can ask the AI chatbot the following question: "What formula can I use in Excel to extract unique values from a range of data?"
UNIQUE formula syntax.
The UNIQUE function in Excel is used to extract unique values from a range or array. Here is a clear and concise overview of its syntax: Syntax: UNIQUE(array, [by_col], [exactly_once]) - array: This is the range or array from which you want to extract unique values. - by_col (optional): This is a logical value that specifies whether to consider the array by column or by row. By default, it is set to FALSE, which means the array is considered by row. - exactly_once (optional): This is a logical value that specifies whether to include only values that appear exactly once in the array. By default, it is set to FALSE, which means all unique values are included. Example 1: Extract unique values from a range (considering by row): =UNIQUE(A1:A10) Example 2: Extract unique values from a range (considering by column): =UNIQUE(A1:E1, TRUE) Example 3: Extract unique values from a range, including only values that appear exactly once: =UNIQUE(A1:A10, FALSE, TRUE) Note: The UNIQUE function returns an array of unique values, so it needs to be entered as an array formula. To do this, after typing the formula, press Ctrl+Shift+Enter instead of just Enter.
Removing Duplicate Rows
This use case demonstrates how to use the UNIQUE function to remove duplicate rows from a dataset. The function returns only the unique rows in the provided range, discarding any duplicates. The rows are returned in the order in which they first appear in the source range.
UNIQUE(range, by_column, exactly_once)
Filtering Unique Values
In this use case, we utilize the UNIQUE function to filter out unique values from a given range. The function returns a list of unique values from the range, removing any duplicates. This can be useful when you want to extract a list of distinct values from a larger dataset.
UNIQUE(range, by_column, exactly_once)
Creating Unique ID
This use case demonstrates how to generate a unique identifier for each row in a dataset using the UNIQUE function. By combining the UNIQUE function with other functions like CONCATENATE or TEXT, you can create a unique ID for each row based on specific columns. This can be helpful when you need to assign a unique identifier to each record in a database or spreadsheet.
