## Find and extract 7 digit numbers starting with a 1 from a column containing other numbers and text

Hi all,

Please could someone let me know how I can extract an 7 digit number that starts with a 1 from a column which contains other numbers (luckily of a different length or which don't start with a 1) and text. It would be great to separate this number and put it in to it's own column if that's possible.

Examples below. As you can see the 7 digit number appears in different places in the column.

 1002223 - 7003117328 - ID: 74526 - Attendance 1046890301 - 210438 1002515 - CW 2047074788 - 210525-1002834 1053847149 - 1016727- 212170 - cw upper

Many thanks in advance for any help.
Marcus

OK, I had better get a kudo for this... 😜

## Re: Find and extract 7 digit numbers starting with a 1 from a column containing other numbers and te

So in the example data provided, what numbers are you looking to extract? In generaly, you are going to use a combination of SEARCH/FIND and probably MID although you might use LEFT or RIGHT as well. Depends.

## Re: Find and extract 7 digit numbers starting with a 1 from a column containing other numbers and te

Hi Greg,

Many thanks for your reply. I'm trying to separate 1002223, 1002515, 1002834 and 1016727 in the examples. But other them beginning with a 1 and being 7 digits long, there is no pattern. I'm hoping there is a way to select them using this criteria so that I can use these numbers (which are work orders) as unique identifiers which allow me to merge data.

Many thanks,

Marcus

Hmm, that is indeed unfortunate as I cannot think how you could have made that problem any harder! I am going to give it a go however, stay tuned.

## Re: Find and extract 7 digit numbers starting with a 1 from a column containing other numbers and te

Hello @mgp-opti

applying some Text.Split and List.Select should to the trick.

Here the complete solution

``````let
Source = #table
(
{"Get Number"},
{
{"1002223 - 7003117328 - ID: 74526 - Attendance"},	{"1046890301 - 210438 1002515 - CW"},	{"2047074788 - 210525-1002834"},	{"1053847149 - 1016727- 212170 - cw upper"}

}
),
(
Source,
"First number with 1 and length = 7 splitting with - or space",
(add)=>try List.First( List.Select(List.Transform(Text.SplitAny(add[Get Number]," -"), each Text.Remove(_,{" "})),(sel)=> Text.Start(sel,1)="1" and Text.Length(sel)=7 )) otherwise "no number with 1 found"
)
in
FirstNumberWith1``````

Copy paste this code to the advanced editor in a new blank query to see how the solution works. If this solution fits your need, copy and past a part of it and implement it in your query

Hi Greg,

You are a total genius - your solution works perfectly! Thank you so much, I really appreciate all the work you put in on this as I know it was a really tough one.

You fully deserve the kudo!

Massive thanks again. This Community is amazing.

Hi Jimmy,

Many thanks for your response, much appreciated. However it looks like I would need to enter the row data in to the query and I've got thousands of rows.

I might  be assuming wrong!

Many thanks anyway.

Best,

Hello @mgp-opti

no, you have to replace my Source-part with your data query and adapt the column-name to your real column.

Understood - sorry!

I'll give it a go and will report back.
