Tip: You can often tell that a number or date is incorrectly formatted as text because it is aligned to the left. The default alignment for text is left and numbers and dates are aligned right.
Unformat Serial Number
Hi, On my excel spreadsheet, I have 2 different columns that are dates formatted X/XX/XXXX. I have used this same spreadsheet for my data for several years now. I opened it this morning and My columns are all in a text format. Instead of the date they all show numbers such as 42572. I have tried re-formatting back to the date but it will not let me. How can I get it to show the date?
As you probably know, a numbers like 42572 is the date serial number. But even if the data in the cell is text, changing the format to short date or long date should convert it to a date e.g. 42572 is 21/07/2016
Hi Kamil,You have to use the ISNUMBER() function to determine if that date is a real numeric date, or is a simple text string that looks like a date. Keep in mind that Excel date system is numeric, but you can format that number to be displayed in many different ways. If a cell contains a text string, excel will return an error. In this case, use DATEVALUE function to convert the text string to a numeric date.Cheers,Catalin
Thanks, Leonid, but your formula still returns a text string, which cannot be used in a formula or PivotTable. The aim of this tutorial was to convert the date text string to a number format in Excel.
The General format is the default number format that Excel applies when you type a number. For the most part, numbers that are formatted with the General format are displayed just the way that you type them. However, if the cell is not wide enough to show the entire number, the General format rounds numbers that have decimals. The General number format also uses scientific (exponential) notation for large numbers (12 or more digits).
For serials, field 362 contains beginning and/or ending alphabetic, numeric, and/or chronological designations of the issues or parts. Chronological designations used in this field are dates that identify individual issues of a serial. In general, publication dates are input in field 260 or field 264. Do not use field 362 for incomplete serial dates. Record uncertain dates/numbers in an unformatted note followed by a question mark.
For integrating resources, field 362 contains beginning and/or ending publication dates when the first or last iteration of the resource is not available. Record publication dates in field 260 or field 264 when the first or last iteration is available. For integrating resources, use field 362 for incomplete dates and only as an unformatted note.
Repeat field 362 only when one of the fields has a 1st indicator value of 0 and the other has a 1st indicator value of 1. When both beginning and ending designations are formatted, or both are unformatted, record them in a single 362 field.
Unformatted note. The date is given in an unformatted note style. Unformatted date information is displayed as a note. Use when the first and/or last piece is not in hand, but the information is known from other pieces or sources.
The sequential designation and/or dates of publication. The sequential designation may consist of edition number, issue number, volume number, series of volume numbers, or other sequential designations according to the usage of the publisher.
Cataloging instructions prescribe four spaces after the hyphen of an open numbering scheme. However, the system displays only one space at the end of a subfield. Therefore, enter only one space after a hyphen that is the final character of subfield ǂa.
If the serial has more than one system of designation, enter all the systems in a single subfield ǂa. Enter space, equal sign, space before an alternative numbering. If the serial is incomplete, enter three spaces after a hyphen that is followed by other data.
If your worksheet has dates that were perhaps imported or pasted that end up looking like a series of numbers like in the picture below, you probably would want to reformat them so they appear as either short or long dates. The date format will also be more useful if you want to filter, sort, or use it in date calculations.
To convert a text date in a cell to a serial number, use the DATEVALUE function. Then copy the formula, select the cells that contain the text dates, and use Paste Special to apply a date format to them.
Excel stores dates as sequential serial numbers so that they can be used in calculations. By default, January 1, 1900, is serial number 1, and January 1, 2008, is serial number 39448 because it is 39,448 days after January 1, 1900.To copy the conversion formula into a range of contiguous cells, select the cell containing the formula that you entered, and then drag the fill handle across a range of empty cells that matches in size the range of cells that contain text dates.
Details: I have a database-like application that reads and writes to an unformatted partition (because it gives me a 40% throughput boost compared to when writing to a regular file). The name of the file that I open is /dev/sda3.
The way to solve this is usually to use persistent device names. However, it seems like one cannot create a persistent name for an unformatted partition. I tried the command: "tune2fs -L newname /dev/sda3", but I get these errors:
However, as with /dev/sdXY, the risk is that if you create/delete a partition on this disk, the partition number may change and you risk to overwrite data on this disk. Both the partition label and UUID are stored within the filesystem, so if you don't use a filesystem, you give the system no way to eliminate the risk of writing on the wrong partition.
Beginning/ending date(s) of an item and/or the sequential designations used on each part. Dates to be used in this field are chronological designations that identify individual issues of the continuing resource. The sequential designations are usually numeric but can be alphabetic as well. The information may be formatted or unformatted. If the date information has been obtained from a source other than the first and/or last issue of the item published, the information is given in an unformatted note and the source of the information is usually cited.
DAYS360 function returns the number of days between two dates based on a 360-day year (twelve 30-day months), which is used in some accounting calculations. Use this function to help compute payments if your accounting system is based on twelve 30-day months.
Old post, but still because it rankes high in google:Excel incorrectly counts the non-existing day 2/29/1900 as day number 60, so if you are converting a date to/from the day number outside of Excel you have to account for this.
A Social Security number consists of three strings of digits separated by hyphens. Historically, the first was an area number, which relates to the resident's geographic location; the second was a group number, which divides each area's SSNs; and the third was a serial number. They now use a more randomized SSN format for security's sake. If you store Social Security numbers for data purposes, you probably don't care about these individual strings, so you can safely remove the hyphens. Use text processing functions to remove the hyphens in Excel and preserve the actual numbers. Additionally, if your business stores Social Security numbers for any reason, make sure that you're storing them in a safe way and complying with any local laws where you do business about storing sensitive personal data.
Social Security numbers are nine digits long and they're traditionally written as three groups of digits separated by hyphens. If you allow people to enter Social Security numbers online, it's likely that some people will include the hyphens and some may not. Some may also include spaces around the hyphens. Internal Revenue Service employer identification numbers, which serve a similar purpose to identify companies rather than individuals, are also nine digits, though they traditionally have only one hyphen after the first two digits.
When you store Social Security numbers or EINs, you might elect to remove the hyphens, since they're not necessary information. You will likely want to add them back if you're presenting the numbers to users, since most people are familiar with seeing the number with the traditional hyphens. Removing hyphens can also make it easier to store EINs and SSNs in the same column, though you'll likely also want to store which is which.
You can use Excel's built-in substitute function to remove or replace a substring of a string of characters in Excel. This can include removing hyphens from Social Security numbers or any other type of string. The function enables you to replace a particular substring of characters in a string of text with a new set of characters or, in this case, with nothing at all. It takes three arguments: a string in which to replace characters, the substring to replace and what to replace it with.
Open the Excel worksheet containing your list of Social Security numbers, or create a new worksheet and enter the numbers in one column. Click on a blank cell to the right of the first Social Security number in your list or add a new column and type this formula:
Click the corner of the cell, with the "+" sign still showing, and drag the cursor down through the column until you reach the cell to the right of the last Social Security number in the list. Release the cursor, and the remaining SSNs will appear without hyphens.
Social Security numbers can be used to fraudulently take out loans, secure employment or receive tax refunds in someone else's name. If you have customer Social Security numbers and they leak or are stolen, your customers will likely be upset. You may also face monetary penalties or lawsuits.
DateNumber = datenum(DateString) converts text representing dates and times to serial date numbers. If the format used in the text is known, specify the format as formatIn.Syntaxes without formatIn are significantly slowerthan syntaxes that include it. 2ff7e9595c
