Serial Number In Excel

Nov 23, 2018 - The serial number, or serial date, is the number Excel uses to calculate dates and times entered into a worksheet. The serial number is. I'm trying to write some VBA code to generate a serial number that uses this format: YYMM-000, where YYMM is extracted from the current date (1708, for example), and 000 is the running number. Apr 23, 2017 - This is because Excel stores dates as a serial number between 1 and 2,958,465 which represent dates between. Use an Excel formula to generate a number series. Put your cursor in the cell at A1. This means the block that is located where Column A meets Row 1. In A1, type =ROW(). This formula should generate the first number in your series. Select the fill handle on the bottom right of the A1 cell, and drag down or across to create the number series. Re: Print Serial Numbers In Excel Spreadsheet Thanks for the quick response. How would I place the same serial number at the bottom of the page (F120) then the next sequential serial number on the other half of the page (R73 and R120). Excel serial number generator; sequential based on week of the year. D using = RIGHT(YEAR(A3), 2) where A3 is date entered. DE = Week in Year (Which I have in hidden column E using =WEEKNUM(A3). FGH = Sequential numbers from 001 to 999. This is the part I can't figure out. I want the first serial number for each week to be 001.

Paste the above formula in column A or where you need to have the serial no; When the second column (For Example, when B column is filled the serial no will be automatically generated in column A).

I have so many records but I need to enter serial numbers automatically in Excel 2007. I have hundreds of records. Instead of entering them manually I want them to show up automatically. Please give me short example for 1 to 10.

you need to fill only starting 2-3 numbers (or text for that matter) and then drag the range down using fill handle. MS Excel will identify the series by itself and will fill the range till where you drag down the range. The below image shows the ‘Fill Handle’.

Enter the formula =ROW() into any cell and that cell will show the row number as its value.

If you want 1001, 1002 etc just enter =1000+ROW()

If you want to pick cell entries from a list then you have a couple of non-code based options

• Data Validation, which is very well covered at Debra Dalgleish's site
• Excel's autocomplete feature

I would recommend The Data Validation approach where

• creating a list of your 100 records in a single column,
• provide a range name to this list,
• then using Data Validation's List option

Simple Answer:

In A1

In A2

copy this down the column. Each time an entry is entered in column B the next number in order will be entered in column A.

Suppose you want the answer of 2 in a4 cell because of your heading & other stuff, you can write as

Enter the first in the series and select that cell, then series fill (HOME > Editing - Fill, Series.., Columns):

It is very fast and the results are values not formulae.

=IF(B1<>',COUNTA($B$1:B1)&'.',')

Using formula

1. Paste the above formula in column A or where you need to have the serial no
2. When the second column (For Example, when B column is filled the serial no will be automatically generated in column A).

I find it easier using this formula

Need to paste this formula at A2, that means when you are encoding data at B cell the A cell will automatically input the serial code and when there's no data the cell will stay blank..you can change the 'IR' to any first letter code you want to be placed in your row.

Hope it helps

I have a very simple answer. Just put this formula in cell A2:

and fill down.

This sets row number automatically, even if you remove some rows or sort rows.

Use formula =row(b2)-x, where x will adjust the entries so that the first S/No is marked as 1 and will increment with the rows.

If you need to calculate dates in your spreadsheets, Excel uses its own unique system, which it calls Serial Numbers. Every date (month, day, year) and time (hour, minute, and second) has an equivalent Serial Number dating back to January 1, 1900 at 00:00:00 (hours, minutes, seconds). Not to be confused with Julian dates, which mainframes and many programming languages use, Excel serial numbers are unique to Microsoft products.

Open Excel and enter the numbers 1 through 5 in cells A3 through A7. Highlight the range, then from the Home tab’s Number group, select Short Date from the drop-down list. Notice that your numbers 1 through 5 have changed to the following dates: 1/1/1900 through 1/5/1900.

Now enter the dates in cells B3 through B7 for the first five days in May; 5/1/2016 through 5/5/2016. Highlight the range; then from the Home tab’s Number group, select General from the drop-down list. Notice that your five dates have changed to the following numbers: 42491 through 42495.

These are the numeric equivalents of the first five days in May of 2016. Excel calls them serial numbers and uses them to calculate dates and times.

Next, enter the following formula in column C to convert Excel’s serial-number dates to Julian dates:

=RIGHT(YEAR(B1),2)& B1-DATE(YEAR(B1),1,0). This is a useful formula if you have to export your spreadsheet data with dates to another program such as a database or timestamp application.

This formula converts Julian dates back to serial dates: =DATE(1900+INT(Julian_Date/1000),1,MOD(Julian_Date,1000))

Number of days between two dates

Magnum P.I. charges $200 a day plus expenses for his services as a private investigator. He wants to know how much money he’ll earn if he works every day from February 21, 2016 through May 1, 2016. Instead of manually calculating this timeframe (accounting for number of days per month, Leap Year, etc.), you can use Excel to quickly solve this problem.

The formula for this calculation is simple: Just subtract the end date from the start date:

=SUM(B1-A1). The answer is 70 days. Now add Magnum’s daily rate to the end of this formula:

=SUM(B1-A1)*200 and you get the answer in one easy formula: $14,000.00. That works out to about $25 an hour—lousy wages even for the 1980s.

Now Magnum wants to know how much he’ll earn if he works the same dates, but takes weekends off. Enter this formula in C3: =NETWORKDAYS(A3,B3). The new answer is 50 days. Or select Date & Time from the Formulas tab, click NETWORKDAYS, and the Function Arguments window opens. Enter the start date and end date in the field boxes or click the corresponding cells (point to them) on the spreadsheet, then click OK. Same answer: 50 days. Now add Magnum’s daily rate to the end of this formula: =NETWORKDAYS(A3,B3)*200 and you get the new salary in one basic step: $10,000.00.

Convert text dates to actual dates

When dates are copied into Excel, they’re often copied as text. Importing dates is a better option but, sometimes, even imported dates come in as text. When this happens, use the DATEVALUE function to convert the text dates to Excel serial numbers. To test this function, enter five dates—as text—in cells A5 through A9. Insert an apostrophe before each date, and that will convert the date to a text entry.

NOTE: When dates are copied or imported into Excel as text fields (from an ASCII file, database, or even a text file), the system automatically reads them as text; however, if you copy a date from MS Word (using copy/paste/text), Excel recognizes it as a date.

Move your cursor to B5. From the Formulas tab, select Date & Time > DATEVALUE. The Function Arguments screen appears. You do not have to re-enter the date in the Date_text field box. Just click the text-date in cell A3, and the Excel serial number appears in cell B5. Copy the formula down to B9.

Now, all you have to do is format the cells to whichever date format you prefer. Highlight cells B5 through B9. From the Home tab’s Number group, select a number format from the General drop-down list. You may also click the tiny arrow in the bottom right corner of this group, and the Format Cells window opens. Select Date from the Category (left panel). Scroll through the date options in the Type panel, and choose the one that fits your project. Now your Excel serial numbers are displayed as actual dates, which means you can use formulas to make calculations.

Serial numbers for all date formats

All businesses use databases and spreadsheets to calculate dates and times daily for payroll, expenses, inventory, sales reports, accounting, and more.

Excel provides serial numbers for all of the date and time formats, from months down to individual seconds. See for yourself: Place your cursor in cell A1. Go to Formulas > Functions and select Date & Time > NOW. Then click OK in the popup window.

From the Home tab’s Cells group, select Format > Format Cells. In the Format Cells window, select a custom date format with minutes and seconds, then click OK.

Next, convert the date to an Excel serial number (as we did above, select the General format from the Home tab’s Number group).

The following formulas convert the serial number to the weekday, month, year, hour, minutes, and seconds. Here’s how.

Go to Formulas > Functions Library and select Date & Time > DAY. When the Function Arguments window opens, point to cell A1 or enter A1 in the Serial Number field box. Excel then displays just the day of the month—in this case, the 9th.

Select the following formulas from the Formulas tab, Functions Library group, Date & Time for cells B2 through B6: MONTH, YEAR, HOUR, MINUTE, SECOND, or enter the following formulas:

=MONTH(A1) returns today’s month

=YEAR(A1) returns today’s year

=MINUTE(A1) returns today’s minute

=SECOND(A1) returns today’s second

All of these formulas can be used separately or with other Date & Time functions to calculate everything from days per quarter; to how many weeks or days between now and Christmas; to how many hours in the month of February on a Leap Year.

Excel Windows vs. Excel Mac

Windows Excel uses the 1900 date system (a carry-over from Lotus 1-2-3), while Excel for the Apple Mac uses the 1904 date system. So the serial number 1 in Windows Excel equals 1/1/1900, 12:00 am, while in Mac Excel it’s 1/2/1904, 12:00 am. Seems like Microsoft should have fixed this by now, but it’s still a problem. Transferring files between the two programs should work because the date system is stored in each file. But copy-and-paste is a different story. Different date systems on different platforms will result in incorrect dates, which will be off by four years and one day.

To make the Apple Mac’s Excel 1904 date system compatible with the Windows Excel 1900 date system:

From the File tab’s Backstage menu, select Options > Advanced. Scroll down the window until you see When Calculating this Workbook (the 10th subhead down the page). Check the box that says: Use 1904 Date System, then click OK.

There are a dozen (or so) more of these type of functions in Excel. Stay tuned for Part Two, which covers the remaining Date & Time formulas with examples.
