Extract specific data from txt file to dt

Hello, I am trying to extract specific data from txt files to a datatable. The txt format is similar to the following, (accounting) but with more lines

Hello, im from Spain
I am learning Uipath
ASSET3 … 003 XXX
ASSET4 … 004 (EMPTY)
Hello, im from Spain
I am learning Uipath
(…) "

I just want to extract the numeric data (XXXX, not 001, 002,…) to a data table. I have thought that I can remove some characters that I don’t need (.) with “replace (”."," “)” And remove some lines that contain useless text. (hello, im from …). How could I erase these lines? RemoveAt (3)? The format of all the txt is the same, same lines with the same information each one, except the amounts, which as you can see, when it is = 0, it does not contain quantity. My goal is to transfer the amounts (XXXX) to a table (in lines or columns) to later copy them to an application. I think I have this Ok. Any ideas? Thank you very much! :slight_smile:

Your best bet would be to look at using Regex to extract the numbers you require, as your example always had 3 digits before the values you can use that.

Take a look at the matches activity.



You can use Regex to solve this.
You can use the Matches Activity with the Regex Pattern:
Regex101.com - Preview the solution here…

However, if you tell us more about the XXXX then I can improve the Regex Pattern to be more robust.

Is the XXXX always a certain length?
Is it just numbers? - Try this pattern if so “(\d{3})\s(\d+)”
Is it just letters?

If you want to learn Regex check out my Regex New User MEGAPOST. There is even a Regex Demo you can download and try for yourself.

Hopefully this can help





A real example down, always are numbers with two decimals (+/-) but i need to extract the “empty boxs” too.

Example of DT i want:

A------------- B
00101 173159,04
00102 0 (or empty cell)

only COLUMN B its important, A its not necessary

Example of my txt:

Hi again!!

I think that i have my pattern OK (thanks to your great megapost) but I can’t get the two groups to “extract” the empty boxes too.
Can you help me with the sequence?

For now I have:
Read PDF Text
For each (item in matchs)
write line (item.tostring)

my pattern: “00\d{3}\s(\d+)\W(\d{2})”

How about?

Thank you very much for your help!!!


Hey @Japp

I am really happy my MegaPost was able to help you! That was the primary goal. Yay! :blush: :partying_face:

Okay - so I believe I have two different options for your Regex pattern. Essentially the + after the “\d” needed to be replaced by a *. The + means there will always be a result (1 or unlimited times). A * means (0 or unlimited times) there might not be a result but could.

Pattern 1:

Pattern 2:

Good luck :slight_smile:


Thats works i think!!! tomorrow i try in UiPath, im on mobile.

Can you help me with sequence to extract to datatable?

A------------- B
00101 173159,04
00103. 6543,56
00106. 363,01



“(00\d{3})\s(\ - * \d * \ ,* \ d *)”

Its my perfect pattern, but im having difficults to extract all the information to a DT.

Okay, so each set of brackets will be a group. You can use these brackets to differentiate your results when putting them into a datatable.

Watch this tutorial in full. Then use it as a guide.

Good luck :blush:

Basic concepts of data table are Ok in this video, but the problem its extract all matches and split in two columns (group 1 and group 2)…

I see this video too, but nothing… He have one match for each pattern and some patterns, and i have some matches and only one pattern…
