Replace Non-Standard Space Characters

The ASCII code for non-breaking space is 160 and along with other chars like 202 which look like space but have different ASCII values cause very frustrating problems for formulas using functions like SUBSTITUTE(). Additionally functions like CLEAN() do not detect these CHARs as they are technical valid within the extended ASCII code set. Fortunately we can replace them with space or other delimiters using the SUBSTITUTE() function in combination with the CHAR() function.

=SUBSTITUTE(SUBSTITUTE(B2, CHAR(202), CHAR(32)), CHAR(160), CHAR(32))

In most cases it will likely be easier to clean the data in bash using tr, sed, and awk. The example below replaces carriage returns with newline and removes all non essential ASCII characters using their respective ASCII codes. Characters can be deleted or replaced by utilizing the -d command parameter. Dive Deeper: https://alvinalexander.com/blog/post/linux-unix/how-remove-non-printable-ascii-characters-file-unix

pbpaste | tr '\r\n' '\n' | tr -c '\11\12\15\40-\176' '\t' | grep ^[[:digit:]] | pbcopy

pbpaste | tr -cd '\11\12\15\40-\176'

You can also attempt to count the total LEN and function off of that result

=IF(LEN(C20)=4,VALUE(LEFT(C20,1)),VALUE(LEFT(C20,2)))

String Manipulation

Split on First Occurrence of Char and return all chars before split point

=MID(D2,1,(FIND(CHAR(1),SUBSTITUTE(D2,":",CHAR(1),1),1)-1))

Split on First Occurrence of Char and return all chars after split point

=MID(D2,(FIND(CHAR(1),SUBSTITUTE(D2,":",CHAR(1),1),1)+1),(LEN(D2)-FIND(CHAR(1),SUBSTITUTE(D2,":",CHAR(1),1),1)))

Split on Last Occurrence of Char and return last 13 characters

=MID(B2,(FIND(CHAR(1),SUBSTITUTE(B2, "PKG-", CHAR(1),((LEN(B2)-LEN(SUBSTITUTE(UPPER(B2),"PKG-","")))/LEN("PKG-"))),1)+LEN("PKG-")),13)

Split on Last Occurrence of Char and return to end of string

=TRIM(RIGHT(SUBSTITUTE(H2," ",REPT(" ",LEN(H2))),LEN(H2)))

Sub-string by occurrence of two characters (extract text between characters)

=MID(A2,SEARCH("(",A2)+1,SEARCH("@",A2)-SEARCH("(",A2)-1)

Date and Time

Excel stores dates as sequential serial numbers so that they can be used in calculations. January 1, 1900 is serial number 1, and January 1, 2008 is serial number 39448 because it is 39,447 days after January 1, 1900. You will need to change the number format (Format Cells) in order to display a proper date.

Remember that Excel stores times as a fraction of a day, so to convert any given time to minutes you simply multiply a time value by the number of minutes in a day (24 * 60 = 1440). You can then divide by the desired time interval, in this case 15.

Days since January 1, 1900 (View Timestamp as Number) = 42602.7936342593

=(("8/21/2016  7:02:50 PM" * 1)

Days since January 1, 1900 (No Change) = 42602.7936342593

=(("8/21/2016  7:02:50 PM" * (24*60))/15)/((24*60)/15)

Multiples of Fifteen = 4089868.18888889

=(("8/21/2016  7:02:50 PM" * (24*60))/15)

Run a FLOOR function Before Converting back into Days = 42602.7916666667

=FLOOR(("8/21/2016  7:02:50 PM" * (24*60)/15),1)/((24*60)/15)

The final result returns the 15 minute grouping (00,15,30,45) rounded down.

=(FLOOR((N4*(24/4)),1)/((24/4)))*24

This also works with any integer, in this case we group days into 4 hour groups.

Index Match on multiple criteria

Return value in respective Index cell

=INDEX(Setup.Benchmark!$F$1:$F$781,MATCH(1,(G2=Setup.Benchmark!$G$1:$G$781)*(I2=Setup.Benchmark!$J$1:$J$781)*(J2=Setup.Benchmark!$K$1:$K$781),0))

Return 1 or 0 based on match

=IF(ISNUMBER(MATCH(1,(G2=Setup.Benchmark!$G$1:$G$781)*(I2=Setup.Benchmark!$J$1:$J$781)*(J2=Setup.Benchmark!$K$1:$K$781),0)),1,0)

Non Printable Characters, VLOOKUP or INDEX MATCH #N/A Error Fix, Solution

=VLOOKUP(TRIM(SUBSTITUTE(D2,CHAR(160),CHAR(32))),'io85'!A:D,4,FALSE)

Excel Help

Important The TRIM function was designed to trim the 7-bit ASCII space character (value 32) from text. In the Unicode character set, there is an additional space character called the nonbreaking space character that has a decimal value of 160. This character is commonly used in Web pages as the HTML entity, . By itself, the TRIM function does not remove this nonbreaking space character. For an example of how to trim both space characters from text, see Remove spaces and nonprinting characters from text.

Sometimes text values contain leading, trailing, or multiple embedded space characters (Unicode character set (Unicode: A character encoding standard developed by the Unicode Consortium. By using more than one byte to represent each character, Unicode enables almost all of the written languages in the world to be represented by using a single character set.) values 32 and 160), or non-printing characters (Unicode character set values 0 to 31, 127, 129, 141, 143, 144, and 157). These characters can sometimes cause unexpected results when you sort, filter, or search. For example, users may make typographical errors by inadvertently adding extra space characters, or imported text data from external sources may contain nonprinting characters embedded in the text. Because these characters are not easily noticed, the unexpected results may be difficult to understand. To remove these unwanted characters, you can use a combination of the TRIM, CLEAN, and SUBSTITUTE functions. 

The TRIM function removes spaces from text except for single spaces between words. The CLEAN function removes all nonprintable characters from text. Both functions were designed to work with 7-bit ASCII, which is a subset of the ANSI character set (ANSI character set: An 8-bit character set used by Microsoft Windows that allows you to represent up to 256 characters (0 through 255) by using your keyboard. The ASCII character set is a subset of the ANSI set.). It's important to understand that the first 128 values (0 to 127) in 7-bit ASCII represent the same characters as the first 128 values in the Unicode character set.

The TRIM function was designed to trim the 7-bit ASCII space character (value 32) from text. In the Unicode character set, there is an additional space character called the nonbreaking space character that has a decimal value of 160. This character is commonly used in Web pages as the HTML entity,  . By itself, the TRIM function does not remove this nonbreaking space character. 

The CLEAN function was designed to remove the first 32 non-printing characters in the 7 bit ASCII code (values 0 through 31) from text. In the Unicode character set, there are additional nonprinting characters (values 127, 129, 141, 143, 144, and 157). By itself, the CLEAN function does not remove these additional nonprinting characters. 

To do this task, use the SUBSTITUTE function to replace the higher value Unicode characters with the 7-bit ASCII characters for which the TRIM and CLEAN functions were designed.

Clean / Trim Non Printing Chars from Excel Data

Removes the trailing space from the string "BD 122 " (BD 112)

=TRIM(A2)

Removes the nonprinting BEL character (ASCII value of 7) from the string value created by the expression ="XY"&CHAR(7)&"453" (XY453)

=CLEAN(A3)

Replaces each nonbreaking space character (Unicode value of 160) with a space character (ASCII value of 32) by using the SUBSTITUTE function, and then removes the leading and multiple embedded spaces from the string " BD   122" (BD 112)

=TRIM(SUBSTITUTE(A4,CHAR(160),CHAR(32)))

Replaces the nonprinting DEL character (ASCII value of 127) with a BEL character (ASCII value of 7) by using the SUBSTITUTE function, and then removes the BEL character from the string "MN987" (MN987)

=CLEAN(SUBSTITUTE(A5,CHAR(127),CHAR(7)))

Count Unique Names / Numbers

The entire formula is as follows (replace C3:C25 with the range of data you want the formula to check)

=SUM(IF(FREQUENCY(IF(LEN(C3:C25)>0,MATCH(C3:C25,C3:C25,0),""), IF(LEN(C3:C25)>0,MATCH(C3:C25,C3:C25,0),""))>0,1))

If you just want to count unique numbers, and not text, use the following formula instead:

=SUM(IF(FREQUENCY(C3:C25, C3:C25)>0,1))

Split string by occurrence of character

Return the portion of string from the second occurrence of character:

=RIGHT($E2;LEN($E2) - FIND("-";$E2;FIND("-";$E2)+1))

Return the portion of string until the first occurrence of character:

=LEFT($E2;FIND("-";$E2)-1)

File Not Found

When starting Microsoft Excel 2004 for Mac OS X you may get the error "File Not Found".

First place to check is the Excel Startup folder:

ljackson 14:46:50 ~/Library/Preferences> cd /Applications/Microsoft\ Office\ 2004/Office/Startup/
ljackson 14:47:33 /Applications/Microsoft Office 2004/Office/Startup> ll

-rw-r--r--   1 ljackson  admin    16K May  3 14:39 Personal Macro Workbook

In my case the alphanumerical file was generated when Excel crashed. So I will delete it:

ljackson 14:47:38 /Applications/Microsoft Office 2004/Office/Startup/Excel> rm -f 8DAE9700 
ljackson 14:47:53 /Applications/Microsoft Office 2004/Office/Startup/Excel> ll

-rw-r--r--   1 ljackson  admin    16K May  3 14:39 Personal Macro Workbook

Now I don't get the anoying error "File Not Found" every time I launch Excel.
