Re: Split field - Qlik Community

Hi

I need to split the following column into 2 columns in the load editor from an Excel file. The first column (Quantity) would include the first numbers and then the second column (Unit) would include all text and numbers after the first numbers in the original column.

Example of the Original column

1 mL

20 pouches

100 T

10 pouches

100 T

10µg

1 mL

4.38 µg/mL in Methanol

1 mL

10µg

1 mL

10 mL

1 mL

10µg

1 mL

10 mL

100 mM * 1 mL in Water

20 pouches

1 mL

20 pouches

1 mL

10 mL

5mg（107.26 mM * 100 uL in Water）

10 pouches

10µg

100 T

1 mL

1mg (3.14 mM * 1 mL in Methyl acetate)

1 mL

10µg

10 pouches

10µg

1 mL-10 pcs

200 μL-2 mL-15 mL

1 mL

10 mL

1 mL

1 ml

1 mL

So the new columns/fields would look like this when split

Original Column	Quantity	Unit
1 mL	1	mL
1mg (3.14 mM * 1 mL in Methyl acetate)	1	mg (3.14 mM * 1 mL in Methyl acetate)
20 pouches	20	pouches
100 T	100	T
10 pouches	10	pouches
100 T	100	T
10µg	10	µg
1 mL	1	mL
4.38 µg/mL in Methanol	4.38	µg/mL in Methanol

The Original column always starts with a number which I need for the Quantity column and then the Unit column always starts with a letter but can also include numbers, spaces, characters etc and the first numbers are not always separated with a space, sometimes they are not separated example '10µg'

Any help would be much appreciated.

Thanks
Paul

hi

try this :

Left("Original Column ",Len(Keepchar("Original Column ",'0123456789'))) as Quantity
Mid("Original Column ",1+Len(Keepchar("Original Column ",'0123456789'))) as Text

Hi @brunobertels

Thank you for your response. I've just tried

Left("Original Column ",Len(Keepchar("Original Column ",'0123456789'))) as Quantity
Mid("Original Column ",1+Len(Keepchar("Original Column ",'0123456789'))) as Text

and it hasn't split some of the field correctly, I get the following for some fields.

Original column	Quantity	Text
2 KU	2.	KU
200 μL-2 mL-15 mL	200 μL	-2 mL-15 mL
1mg (3.14 mM * 1 mL in Methyl acetate)	1mg (	3.14 mM * 1 mL in Methyl acetate)
2.5 mg	2.	5 mg
2.5g	2.	5g
2.5kg	2.	5kg
2.5mg	2.	5mg
7.5mg	7.	5mg
5mg（107.26 mM * 100 uL in Water）	5mg（107.2	6 mM * 100 uL in Water）
4.38 µg/mL in Methanol	4.3	8 µg/mL in Methanol
2g	2.	g
1 mL-10 pcs	1 m	L-10 pcs
2mg	2.	mg

I've attached a file that has the original column that needs splitting.

Thanks
Paul

Hi

Due to complex string the solution is a little bit harder

after some research in the forum, try this script who works for me.

1 script example :

I did 2 preceding load to show who how to extract NUMBER end the how to extract TEXT

but at he end you can concatenate twice to create the dimension Quantity and the dimension Text :

see script example 2

Table1 :

load *,

// préceding load to extract from the column Original the text value without the first number part of the string

mid(Original_column_Quantity,
len(Quantity)+1) as Text;

Load *,

// preceding load to find only first value in string who is a number (can be 1 , 2 , 3.8 etc ) named as Quantity

Mid(Original_column_Quantity,FindOneOf(Original_column_Quantity,'.0123456789'),FindOneOf(Mid(Original_column_Quantity,
FindOneOf(Original_column_Quantity,'.0123456789')),PurgeChar(Original_column_Quantity,'.0123456789'))-1) as Quantity;

// load the column to plit :

load * Inline [
Original_column_Quantity,
2 KU,
200 μL-2 mL-15 mL,
1mg (3.14 mM * 1 mL in Methyl acetate),
2.5 mg,
2.5g,
2.5kg,
2.5mg,
7.5mg,
5mg（107.26 mM * 100 uL in Water,
4.38 µg/mL in Methanol,
1 mL-10 pcs,
2mg,
](delimiter is ',');

Table2:

Load *,

Mid(Original_column_Quantity,FindOneOf(Original_column_Quantity,'.0123456789'),FindOneOf(Mid(Original_column_Quantity,
FindOneOf(Original_column_Quantity,'.0123456789')),PurgeChar(Original_column_Quantity,'.0123456789'))-1) as Quantity,

mid(Original_column_Quantity,
len(Mid(Original_column_Quantity,FindOneOf(Original_column_Quantity,'.0123456789'),FindOneOf(Mid(Original_column_Quantity,
FindOneOf(Original_column_Quantity,'.0123456789')),PurgeChar(Original_column_Quantity,'.0123456789'))-1))+1) as Text;

load * Inline [
Original_column_Quantity,
2 KU,
200 μL-2 mL-15 mL,
1mg (3.14 mM * 1 mL in Methyl acetate),
2.5 mg,
2.5g,
2.5kg,
2.5mg,
7.5mg,
5mg（107.26 mM * 100 uL in Water,
4.38 µg/mL in Methanol,
1 mL-10 pcs,
2mg,
](delimiter is ',');

the resulting table should look like this

hope it helps

also using this FindOneOf/PurgeChar approach, a shorter solution might be as well:

table1:
LOAD *,
     Left(OriginalColumn,FindOneOf(OriginalColumn,PurgeChar(OriginalColumn,'0123456789.'))-1) as Quantity,
     Trim(Mid(OriginalColumn,FindOneOf(OriginalColumn,PurgeChar(OriginalColumn,'0123456789.')))) as Unit
INLINE [
