How to reshape data trapped in 1 field to many?

hellyars

Hi,  

 

The data source is a daily email of announcements.   The data is trapped in one initial output field.   I need to reshape it.  I am thinking transpose, parse, multi-role formula, etc.  But, I don't know where to begin.  Thanks

 

My first step is to import the email as a TXT file.  I have Delimiter import options set to \n.   I can filter some of the header information using the Start Data Import on Line setting.  The data table below represents the initial output of the Input Tool.

 

I need to parse, transpose the data into columns and rows.   The tables below depict 1) the data after import and 2) the desired output.

 

A few things...

 

There are 3, sometimes 4 categories.   They are always named the same (CATEGORY A, CATEGORY B, CATEGORY C, CATEGORY D).  The number of items under each CATEGORY (represented by the Lorem Ipsum) can vary from 0 to N on a day-to-day basis.  And, I want to ignore everything after "END" statement, which in the real world is *small business".

Okay.

 

 

I found one way to breakout and fill-in for Category.

 

1.  I created a new field using the Formula tool.  

if [Field_1]='A' then 'A' 
elseif [Field_1]='B' then 'B'
elseif [Field_1]='C' then 'C'
elseif [Field_1]='D' then 'D'
else Null()
endif 

2.  I then used the Multi-Row Formula tool to 'fill-down'. Check out this Tool Mastery | Multi Row article.

 

iif(isnull([Category]),[Row-1:Category],[Category])

Based on the sample you provided I suggest:

2018-12-30_17-43-09.png

 

1. Use a multi row formula to create the date column. I used REGEX_Match to look for a date and then DateTimeParse to parse:

IIF(Regex_Match([Field1],"[A-Z][a-z][a-z] \d{2},\s+\d{4}"),
    DateTimeParse([Field1],"%b %d,%Y"),
    [Row-1:Date])

2. Use a second multi row formula to make the category. Again I chose Regex to match the category text:

IIF(Regex_Match([Field1],"^CATEGORY .*"),
    [Field1],
    IIF([Field1]="End",NULL(),[Row-1:Category]))

3. Finally filter to rows with a Category and then a select to tidy up

 

Sample attached.

I love the simplicity of this approach.  I just came up with my own solution, but I think this approach provides more flexibility should any anomalies creep up in the source data.  It also requires 1/3 the steps.

 

 

Many Thanks

@jdunkerley79.  

 

How might you modify the 2nd Multi-Row/Regex formula if Category was A, B, C, D and NOT Category A, Category B, Category C, and Category D?

 

Thanks

Assuming you know the list of categories I would suggest:

 

IIF([Field1] IN ("A","B","C","D"),
    [Field1],
    IIF([Field1]="End",NULL(),[Row-1:Category]))

 

Otherwise, you will need to come up with some rule to identify the category cells. Feel free to DM me if you want me to look at real list in private
