DATEVALUE function

PRO BASIC

The DATEVALUE function in Jspreadsheet Formulas Pro is a tool that changes a text string representing a date into a serial number, wwhich Jspreadsheet recognizes as a valid date value. This is useful when working with dates stored as text that need to be converted for use in date calculations or formatting. For example, the text '1-Jan-2020' can be converted into the serial number 43831, which Jspreadsheet identifies as a date. This function is a helpful way to manage and manipulate date data within your spreadsheet.

Documentation

Converts a text string that represents a date to a serial number that Excel recognizes as a date.

Syntax

DATEVALUE(date_text)

Parameter	Description
`date_text`	A text string that represents a date in a recognizable format. For example, "2022-01-01" or "January 1, 2022".

Behavior

The DATEVALUE function converts a date that is stored as text into a serial number recognized as a date. For example, "1/1/2021" as text can be converted to the date serial number 44197. The serial number represents the number of days passed since January 1, 1900, which is the system used to calculate dates.

When an empty cell is referenced, the DATEVALUE function will return a #VALUE! error.
For text, if it represents a valid date, DATEVALUE will convert it into the corresponding serial number. If the text does not represent a valid date, a #VALUE! error is returned.
Booleans are not valid arguments for the DATEVALUE function and will return a #VALUE! error.
If the function encounters an error value in its input, it will propagate that error to its output.

Common Errors

Error	Description
#VALUE!	The input is not a valid date, is non-numeric, or the function encounters an empty cell.
#REF!	The cell reference is not valid. This could be due to deleting a row, column, or cell that the function is referencing.

Best practices

Always ensure that the date text you are trying to convert is in a recognized date format. If the date text is not in a correct format, the DATEVALUE function will return a #VALUE! error.

Use error handling functions like 'IFERROR' or 'ISERROR' along with DATEVALUE to handle any possible errors and maintain the cleanliness of your data.

Avoid referencing empty cells within your DATEVALUE function to prevent unwanted #VALUE! errors.

Use DATEVALUE in conjunction with other date functions for more complex date manipulations and calculations.

Usage

A few examples using the DATEVALUE function.

DATEVALUE("2022-03-15") // Returns: 44635
DATEVALUE("2025-12-31") // Returns: 46022
DATEVALUE("2024-02-22") // Returns: 45344
DATEVALUE("January 1, 2020") // Returns: 43831
DATEVALUE("1/1/2021") // Returns: 44197
