excel vba Delete entire row if cell contains the GREP search - excel

I have a single column of text in Excel that is to be used for translating into foreign languages. The text is automatically generated from an InDesign File. I would like to clean it up for the translator by removing rows that simply contain a number ("20", 34.5" etc), or if they contain a measurement "5mm", "3.5 µm", etc. I've found many posts (see link below) on how to remove a row with specific string, but none that use search strings, such as those I typically use with GREP searches: "\d+" and "\d.\d µm"
How would I do this? I am on Mac iOS if that helps.
Note that I would need to delete the row if the cell only contains a number or a measurement, not if the number is contained within a phrase, sentence, or paragraph, etc.

It may not be what you are looking for, but how about just sorting the column and remove the rows starting with numbers? It is a manual approach but from what I understand this translation process only happens from time to time. Am I right?

I see two possible issues in your question:
How to work with regular expressions in Excel?
How to delete rows in a loop?
Let me start with the second question: when you want to create a for-loop in order to remove items from a list, you MUST start at the end and go back to the beginning (it's a beginner's trick, but a lot of people trip over it.
About the first question: this is a very useful post about this subject, it's too large to even give a summary here.

How to search for items with multiple "-" in excel or VBA?

I have a list of item numbers (100K) like this:
Some of the items have format like SAG571A-244-4 (thousands) which need to be filtered so I can delete them and only keep the items that have ONE hyphen per SKU. How can I isolate the items that have two instances of "-" in it's SKU? I'm open to solutions within Excel or using VBA as well.
Native text filters don't seem to be capable of this. I'm stumped.
As per John Coleman's comment, "*-*-*" can be used to isolate strings that have at least two dashes in them.
I would add that if you're entering them as a custom text filter, you should lose the double quotes (so just *-*-*) as otherwise the field seems to interpret the quotes literally.
Seems to work for me.
If you want just an excel formula to verify this and give you a result of the number of hyphens (0, 1, or 2+), here is one:
=IF(ISERROR(SEARCH("-",A1)),"0",IF(ISERROR(SEARCH("-",A1,IFERROR(SEARCH("-",A1)+1,LEN(A1)))),"1","2+"))
Replace A1 with your relevant column, then fill down. This is kind of a terrible way to do this performance wise, but you avoid using VBA and possibly xlsm files.
The code first checks to see if there is one hyphen, then if there is it checks to see if there is another hyphen after the position the first one was found. Looking for multiple hyphens in this manner is cumbersome and I don't recommend it.

Is there a way to replace cells of a particular value with multiple cells?

Let's say I need to replace any cell that has a value of "outgoing" with multiple cells such as (0), (1), (0), (0), (2), in Excel. Is there a way to actually make this happen? I am doing this for a research project. Every item in my data needs to be coded on five different scales. There are 30-or-so items make up for almost half of the data. It would be enormously helpful to be able to simply replace the high frequency items with the five values at once.
I am not sure I completely understand the result you are looking for but here goes:
How about using the Find and Replace functionality to replace all instances of "outgoing" with "(0),(1),(0),(0),(2)" and then use the Text to Columns functionality to split the single column with "(0),(1),(0),(0),(2)" in to five separate columns, thus each value would be in its own cell.
You would need to split based on a delimiter (probably ",") and you should do all your replacing before you start splitting. Obviously you should test on some sample data first - Find and Replace is not your friend if you are not certain about your data set.

Excel conditional formating based on the multiple cells and values

I am trying to implement various conditional formatting to a specific data base. Looked for answer around here but can not find anything similar. Might not be possible but it is worth a try.
I am preforming various data cleansing and validation.
Here is the case: (small sample, working with 100k data entries in this particular file)
Ultimately what I want is the formula that will compare the low-level Description characters after the last "UNDERSCORE" to the characters after last "UNDERSCORE" of the higher level(highlighted). If it does not match then highlight the cell?
Asking for too much, yes, no, maybe? I am open to any other suggestions on how can I perform various data cleaning and validation!
Thank you!
If you must use the last "UNDERSCORE" character, and can't depend on the suffixes being four characters, the formula becomes quite complex. For simplicity's sake, I assumed the higher level is always missing the last five characters of the lower level, if you must go by the last "DASH" character, then this will be a lot longer.
Use this formula to highlight the cells, defining the two names LEVELS and DESCRS to be the two columns:
=IFNA(MID(B2,FIND("[]",SUBSTITUTE(B2,"_","[]",LEN(B2)-LEN(SUBSTITUTE(B2,"_",""))))+1,999)<>MID(INDEX(DESCRS,MATCH(LEFT(A2,LEN(A2)-5),LEVELS,0),1),FIND("[]",SUBSTITUTE(INDEX(DESCRS,MATCH(LEFT(A2,LEN(A2)-5),LEVELS,0),1),"_","[]",LEN(INDEX(DESCRS,MATCH(LEFT(A2,LEN(A2)-5),LEVELS,0),1))-LEN(SUBSTITUTE(INDEX(DESCRS,MATCH(LEFT(A2,LEN(A2)-5),LEVELS,0),1),"_",""))))+1,999),FALSE)
This uses a very nice trick with SUBSTITUTE to find the last occurrence of a character.
BTW, I would probably write a Perl program to parse the data and find errors.

Excel, Numberplate Clarification

I am working on an excel document for fuel cards at the minute and my current issue is to write in a formula for validating number plates based on UK standard plates (two letters followed by two numbers then three letters i.e. BK08JWZ). At this point in time we are not considering personal plates in this just to keep things simple.
Ideally I need excel to look at the text in the box and confirm it to an agreed layout but I am struggling to find the right formula. The plates are in column 'I' and I have already added in another column after titled 'approved plates' in column 'J'but this can be deleted if it's not needed.
Results wise, I can do this one of two ways, to either get the excel document to highlight and number plates that do not match the DVLA standard , or have a column next to the number plate column that registers a boolean response to the recognition i.e. If it is valid (true) or if not (false).
Either way the plate needs to be able to be seen as it was currently, so if there is something wrong with it, it needs to be visible, not throw up an error message.
Any help would be very welcome.
All the information on UK standard number plates are on this site:
https://www.gov.uk/government/uploads/system/uploads/attachment_data/file/359317/INF104_160914.pdf
I would do it like this:
1) create a lookup sheet with data from the booklet. One column for allowed "memory tag" identiffiers (first two letters), one column for the allowed "age identiffiers" (first two numbers), and one column for allowed random letters (last three letters, full alphabet except I and Q)
2) strip spaces from the number plate for comparison
3) Use MID(numberplate,1,2), MID(numberplate,3,2) and MID(numberplate,5,3) to compare to each lookup list repectively (using INDEX()>0).
4) when all 3 parts are found in lookup lists the number plate is valid.
Try researching Regular Expressions or RegEx. This is a powerful programming tool to determine whether strings match specific patterns. You can use RegEx expressions to extract the pattern, replace the pattern or test for the pattern. Very efficient but not for the faint-hearted although there is plenty of help on-line. Try this article for starters.
The following RegEx may be what you need..
(?^[A-Z]{2}[0-9]{2}[A-Z]{3}$)|(?^[A-Z][0-9]{1,3}[A-Z]{3}$)|(?^[A-Z]{3}[0-9]{1,3}[A-Z]$)|(?^[0-9]{1,4}[A-Z]{1,2}$)|(?^[0-9]{1,3}[A-Z]{1,3}$)|(?^[A-Z]{1,2}[0-9]{1,4}$)|(?^[A-Z]{1,3}[0-9]{1,3}$)
This was copied from this article which gives a very full explanation using DVLA rules.
EDIT:
To use RegEx within Excel. In the IDE, Tools menu, select References and add the Microsoft VBScript Regular Expressions 5.5 reference.

Mid Function for Microsoft Excel to obtain column .txt file

Captain Morgan ------ Insane Journeys -------- A-
I have easily gotten the left and right side parts using Left() and Right() functions.
I want to use a function in excel (not vba) that will allow me to get the middle phrase in this sentence (The dashes are really excessive spaces). can I accomplish this with a Mid() function?
This is just 1 item on a list of 80 different things in 1 column that needs to be turned into 3 columns. Every item has different character lengths. So the length counts cannot be manually entered.
I agree with Text to Columns but the image in the other answer only has one space per row while OP has some spaces that are redundant and some that are not. For this I’d suggest a modified approach:
Replace all pairs of spaces with a character unlikely to be encountered – I’d suggest a pipe.
Apply Text to Columns with pipe as delimiter.
Apply TRIM to the middle column to remove any remaining redundant spaces (eg =TRIM(B1) copied down and then that column pasted as values over the source).
But to answer can I accomplish this with a Mid() function? I think yes though not cost effective for a mere 80 entries when there is a viable alternative.
Try to use "Text to columns" from Data Tab. It has option to split data to different columns using various criteria.
All you need to do is select data you want to split to columns and select criteria you need.
In your case it can be either Space or Other:. When you select Other: you can add your own criteria like "space dot space" or anything you need.
