This thing motivated Microsoft to develop another spreadsheet product Excel.The first version of Excel was released in 1985 for Mac. Later in November 1987, the first Windows version was released. It all started with VisiCalc: In 1978, Harvard Business School student Dan Bricklin developed a program called VisiCalc. It has been a very widely applied spreadsheet for these platforms, especially since version 5 in 1993, and it has replaced Lotus 1-2-3 as the industry standard for spreadsheets. Excel forms part of the Microsoft Office suite of software. YEAR is an inbuilt function in excel that can be used both as worksheet function and VBA function in excel. For Example, =YEAR (2018-11-25) would return the result as 2018. It does not matter whether the date is in date format or date & time format.

The immediate solution is to import the data again while identifying that field as a date. But if that isn't possible, you can correct the data by creating a table that contains the dates along with their Excel number values.
THE TABLE
The import error occurs because Excel stores dates as the number of days since 'January 0, 1900.' As you import the data into your database, Access sometimes treats the data as text. This can happen, for example, when the first row of imported data is blank. The result is numbers instead of formatted dates, for example, 42237 instead of 8/21/2015 or 41795 instead of 6/5/2014.
To create the table that will contain dates and their corresponding Excel number values, first open a new spreadsheet in Excel. Label column A as 'Numbers' and column B as 'Dates. Add the numbers from 1 to 50,000 in column A and their corresponding dates of 1/1/1900 to 11/22/2036 in column B.
To create the list of numbers, enter the value 1 into cell A2. With that cell selected, go to the Home tab and click on the Fill dropdown in the Editing group. Select Series… to open up the Series dialog box. Make sure the Columns and Linear options are selected and that the Step value is 1. Set the Stop value to 50000 (see Figure 1). If you need dates farther into the future, set the Stop value to a larger value. Click OK. Column A now contains the list of numbers from 1 to 50,000.
Now add the dates to column B. The quickest way is to copy the numbers in column A into column B and then change the format to Date. Another quick method is to put the date 1/1/1900 in cell B2 and then double-click the Fill handle.
Finally, import the spreadsheet into your Access database. Make sure the first field is imported as text and the second field as dates. Name the table 'Excel Numbers to Dates.' Project 64 open source.

UPDATE THE DATES
Now that the table is in Access, create a query to update the dates. To help illustrate this issue, I added a simple table named 'CashTransactionHistory' to our test database. As you can see in Figure 2, the Date field contains number values rather than formatted dates. Also note that I added a field called 'Transaction Date.' We'll use this in our query to hold the updated (i.e., formatted) dates.
Create a query using the Excel Numbers to Dates and CashTransactionHistory tables as data sources. Link the tables by dragging the Number field in the Excel Numbers to Dates table to the Date field in the CashTransactionHistory table. This links the number values in both tables. Change the query to an update query. Bring down the Transaction Date field and type [Excel Numbers to Dates].[Date] into the Update To row. Run the query. The Transaction Date field will be populated with the date that corresponds to the sequence number in Excel. Save the query as 'Update Date Text to a Date' and close it.
Unless you see a need to keep the improperly imported data, go into Design view for the table and delete that field. For our example, open the CashTransactionHistory table in Design view and select the Date field. Press the Delete key. Confirm the delete. Now it will only have data with accurately formatted dates. Before leaving Design view, rename the Transaction Date field to 'Date' so that the field has the proper name for any queries that may have been using the old Date field. Save the table.
READER QUESTION
Recently I received a reader question about how to change the sign of a calculation result from negative (-) to positive in a report control. The answer is very straightforward: multiply the entire calculation by -1. In order to do this, put parentheses around the entire calculation and add a minus sign to the beginning. In the case of a negative result for a calculation, it will be changed to a positive.
This strategy works for any calculation where you want to reverse the sign. You would do the same thing if you wanted to put a negative sign in front of a calculation result that turned out positive. Here's an example using a complex expression:
What Year Did Excel Come Out
=-(Sum([TotalAmountPayable]+[VAT]+[LocShip])-([PriceSp])-([AllocatedBudget]))
Note the –( at the beginning and the ) at the end. That's all that's needed to change the sign. This will work in a report control, a query, or anywhere else you use a calculation. Thanks for reading and asking questions.

Saving the update query even though it's a one-time update is a way to document the solution to a problem that you may encounter again. You can also print out the query or create a documentation folder to keep a record of these handy solutions.
