Excel represents dates and times as serial numbers. Correct cell formatting is essential for displaying these numbers as dates. Local computer settings influence how Excel interprets dates.
The DATE function can create a date from separate year, month, and day values. For an 8-digit number in the format YYYYMMDD, use the formula =DATE(LEFT(A1,4), MID(A1,5,2), RIGHT(A1,2))
to convert it to a date.
The Text to Columns wizard in Excel can transform text strings into dates. This feature adjusts text dates by adding zeros when necessary and respects the cell's number format.
The Ultimate Suite for Excel offers the Text to Date tool. It can convert text strings in various formats to dates with one click, without the need for complex formulas.
To change a number to a date format, use the Format Cells dialog. This ensures that numbers are represented as dates and can include time values if required.
Complex date strings can be converted using formulas. For example, the ICAO format YYMMDDhhmm can be changed to a date and time with =DATE(MID(A1,1,2),MID(A1,3,2),MID(A1,5,2))+TIME(MID(A1,7,2),MID(A1,9,2),0)

Use the formula =DATE(LEFT(A1,4), MID(A1,5,2), RIGHT(A1,2)) where A1 contains your 8-digit number in YYYYMMDD format. This formula uses the DATE function combined with LEFT, MID, and RIGHT functions to extract and combine the year, month, and day values.
Excel stores dates as serial numbers but uses cell formatting to display these numbers as dates. To properly display the converted 8-digit number as a date, you need to ensure the cell has the correct date format applied.
You need to use the DATE function along with three substring functions: LEFT to extract the year, MID to extract the month, and RIGHT to extract the day. These functions work together to split the 8-digit number into its components and reconstruct it as a proper Excel date.
Converting 8-digit numbers to dates in Excel can be complex without the right tools and knowledge. While Excel's built-in functions can handle this task, many users struggle with the correct syntax and formatting.
