To convert a 2-digit year to a 4-digit year in Excel, use Custom Formatting (type yyyy) for visual changes, or use a formula like =DATE(IF(A1>50,1900,2000)+A1,1,1) (adjusting logic for your needs) to create a real 4-digit date in a new cell, especially useful when Excel misinterprets text dates, often involving the Text to Columns feature or smart tag correction for imported data.
Click the Date tab. In the Short date format list, click a format that uses four digits for the year ("yyyy"). Click OK.
We can just open the Format Cells dialog by pressing Ctrl + 1. After that, select the Custom category on the Number tab, and enter one of the codes below in the Type box: yy – to display 2-digit years, as 00-99. yyyy – to display 4-digit years, as 1900-9999.
Create 4-Digit Numbers with Precision
In Microsoft Excel, Ctrl+F12 is a shortcut that opens the "Open" dialog box, allowing you to browse for and open an existing workbook file, similar to going to File > Open. It's a handy way to quickly access your saved files without using the mouse, though on some laptops you might need to press Ctrl + Fn + F12.

Methods to Remove Scientific Notation
To convert 2-digit YEAR(2) columns to 4-digit YEAR columns, you can do so manually at any time without upgrading. Alternatively, you can upgrade to a version of MySQL with reduced or removed support for YEAR(2) (MySQL 5.6. 6 or later), then have MySQL convert YEAR(2) columns automatically.
Follow these steps:
Ctrl+H Displays the Find and Replace dialog box, with the Replace tab selected. Ctrl+I Applies or removes italic formatting. Ctrl+K Displays the Insert Hyperlink dialog box for new hyperlinks or the Edit Hyperlink dialog box for selected existing hyperlinks.
If you want to maintain the original cell reference in this example when you copy it, you make the cell reference absolute by preceding the columns (B and C) and row (2) with a dollar sign ($). Then, when you copy the formula =$B$4*$C$4 from D4 to D5, the formula stays exactly the same.
How to Change the Date Format in Excel
You can use the QUARTILE() function to find quartiles in Excel. If your data is in column A, then click any blank cell and type “=QUARTILE(A:A,1)” for the first quartile, “=QUARTILE(A:A,2)” for the second quartile, and “=QUARTILE(A:A,3)” for the third quartile.
Unfortunately excel does not allow you to turn this functionality off by default. However if you select your data, right click, and click "Format cells..." and choose Number you can stop excel from changing your data to scientific notation.
Note the numbering format when you enter numbers in a CSV file. By default, many spreadsheet programs don't permit or don't show leading zeros, which can be a problem if your data needs those leading zeros. You can resolve this issue by formatting the cells in the spreadsheet program as text rather than numbers.
On the Data tab, in the Get & Transform Data group, click From Text/CSV. In the Import Data dialog box, locate and double-click the text file that you want to import, and click Import. In the preview dialog box, you have several options: Select Load if you want to load the data directly to a new worksheet.
The Scientific format displays a number in exponential notation, replacing part of the number with E+n, in which E (exponent) multiplies the preceding number by 10 to the nth power. For example, a 2-decimal scientific format displays 12345678901 as 1.23E+10, which is 1.23 times 10 to the 10th power.
A number in exponential form is written by taking the base number used as a factor multiple times, and raising it to the power of the number of times it is used as a factor, for example, 3 to the fourth power is 3x3x3x3, or 3 multiplied by itself four times.
By default, when you enter a number over 12 digits in an Excel spreadsheet, it auto-corrects the number to scientific notation for brevity. For example, "879860004073" is converted to "8.7986E+11". When Excel exports the value to a CSV or Text file, it will export what you see, not the actual 12-digit value.
4-digit numbers are those numbers that consist of only 4 digits in which the first digit should be 1 or greater than 1 and the rest of the digits can be any number between 0 and 9. For example, 5693, 1023, and 9825 are four-digit numbers.
