Wow, fantastic tutorial! I work as an accountant, and Linda from HR, who, and this is between us, is thick as a brick, keeps sending us the payroll tables as PDFs. As an accountant, I need my tables in the Excel software so that I can generate the macros for the supervisors' meetings on every second Thursdays. Thanks to your brilliant, amazing tutorial, what used to take 4 hours (not counting lunch time) now takes 15 minutes tops! I have been able to use my remaining 3h45 minutes to clean-up my Desktop folders, entertain myself to some sudoku, and n0sc0pe h8ters on the LoL game. Thank you again Mr. Sv, very much appreciated!
Very concise but detailed explanation even for new Python user like me. Also the video is very easy to follow, and is organized logically. Very valuable 14 minutes I spent watching this. Thank You.
@@ajarivas72 I am not sure about that, please feel free to explore using the code provided in the tutorial and update me in the comments section here. I'd be curious to know if it works for both vectorized data and images of tables!
Thank you that's very helpful, i just have a question what if I have the same table repeated in multiple PDFs and I need to append them to one csv file
Thanks a lot for all your efforts to makes understand the pdf table extraction. 😇🥰 I'm now able to fetch tables from un structure format pdfs. Once again thanks a lot
After- print(len(dfs)) I got "SyntaxError: (unicode error) 'unicodeescape' codec can't decode bytes in position 2-3: truncated \UXXXXXXXX escape" could you tell me what's the problem? Solved it 1: Just put `r` before your normal string. It converts a normal string to a raw string:

Hi I have one big table that carries on through each page but each page is technically it’s own table with new headers so is there anyway to append all of these tables in one file and remove the headers so that it becomes one long csv file with only one set of headers
That would be a more complex operation for the standard functionality to handle. I suggest looking at their full documentation here: tabula-py.readthedocs.io/en/latest/
CalledProcessError: Command '['java', '-Dfile.encoding=UTF8', '-jar' returned non-zero exit status 1. I'm getting the above error, even after installing latest version JVM, any help would be very much appreciated
Hi, your work is fantastic and I am amazed at that! But just wondering would Python can do if I need to extract specific tables that are located on different pages for different files? I have more than 200 pdf files, each pdf has a different amount of pages, some have only 5 but some have 10. I need the table with the word “statement total” so that I can extract the data under “quantity” & “amount” in each of the tables. Currently, my workflow is that (open pdf - scroll to the page that has statement total - search for a page with statement total - look for the amount under "quantity" & "Amount" - copy and paste into my excel - then close the pdf file. Hope to seek some advice from you, thanks
This would probably require multiple steps. You will have to first find the relevant page with the text that says "statement total", then get the page number, and then extract the table from that page. You will have to do it for every PDF file. It can be difficult since tables can take multiple pages as well. It's definitely doable but requires some amount of custom code for it including finding the correct text and then extracting the tables.
@@kennethgomes4727 I would try the library fitz, it reads text in a pdf, you can store it in a dictionary using page number as key and text as value, from there you can run a search of your text and get the relevant page number where you can find your table hope it helps
It depends on how the original PDF was created. If it has images of tables inserted then the script might not get it from the PDF. It will only work if the tables were originally created as tables in the PDF.
I found that by opening a pdf file with Mozilla Firefox and inspecting it with the developer tools you can collect its text (with the help of JavaScript) after the web browser has converted it to HTML and maybe save it for further processing with someone programming language.
The thing is whether it is tabula Or camelot they don't read all the tables, I want to extract tables from research papers but my rag pipeline in which I have used tabula Or camelot for doing it fails in covering all the cases, so do we have any other solution.
@ammariskandar9939 yupp I got the solution. We needed it for complete table extraction for our Advance RAG Project as a part of our internship. So we used Paddleocr and PPStructure for it. It completely extracts table along with maintaining its structure too.
You should watch a section from 7:00 in the video. If you run tabula.convert_into() function as shown in the tutorial and setpages="all" or whatever the numbers of pages are, and it will write all tables into a single CSV file, and you would then need to separate the tables manually.
@@MishaSv Good luck trying to explain that to them. They wanted to stop users from uploading confidential files to random conversion sites and I tried power automate, ai models and python
Good video. Nothing against the video but the library is not perfect. I was quite excited that I will get to extract data from my etrade statement files (pdf) but whether I run it for all pages or page by page, it skips certain tables or part of the tables. I have a suspicion when a table is continued from one page to the next, the logic hits a glitch and becomes very unpredictable for that page.
Yes, the library has its limitations and this tutorial is just to showcase some of the functionality. It works best when a table is well defined and is on one page. The moment it becomes split across multiple pages, you need to customize the code to retrieve the table as a whole by concatenating several dataframes.

Is going well too with tables without "lines"?
Thank you!
Super clever tutorial Misha, in 10 minutes you gave me what I was looking for. Keep up the good work!
Thank you!

Does it work when the tables are pictures instead of vectorized data?

finally a tutorial where i can finally get a kitchen table out of my computer...
wait did i miss something...
Thanks a lot, it helps so much, greetings from Peru
Thank you!
Well explainted in the short time, thanks, Misha!
Thank you!
Thank you that's very helpful, i just have a question what if I have the same table repeated in multiple PDFs and I need to append them to one csv file
If the PDF files are placed in the same folder, then you can iterate over multiple files, extract tables from each one, and then append them together.
Thanks a lot for all your efforts to makes understand the pdf table extraction. 😇🥰 I'm now able to fetch tables from un structure format pdfs. Once again thanks a lot
thank you Misha...Very clear and useful your video!! TKS!!
Hey, how can i solve this?
No JVM shared library file (jvm.dll) found. Try setting up the JAVA_HOME environment variable properly.
I have the same problem, you managed to find any solutions..?
After- print(len(dfs)) I got "SyntaxError: (unicode error) 'unicodeescape' codec can't decode bytes in position 2-3: truncated \UXXXXXXXX escape"
could you tell me what's the problem?
Solved it 1: Just put `r` before your normal string. It converts a normal string to a raw string:
nobody got error:
AttributeError: module 'tabula' has no attribute 'read_pdf'
?
Install tabula-py in addition to tabula. Otherwise, it wont work
Thank you Mr.
Good tuturial, thanks.

Hi I have one big table that carries on through each page but each page is technically it’s own table with new headers so is there anyway to append all of these tables in one file and remove the headers so that it becomes one long csv file with only one set of headers
What do you do if the table continues on multiple pages?
it creates a list of dataframes by setting 'all' as pages
Thanks, a great video!
Do I need to install visual code, I already installed the python and java, ?? please answer immediately,, Thank you
No you don't. You can run the code as .py file from any editor or from terminal.
Really good vedio...how can we data into single file with multiple tabs
You will have to write out each tables as a separate .csv file after it's extracted from the PDF.
What if a table is split across multiple pages and the headers have multiple rows that are split into 'columns" differently?
That would be a more complex operation for the standard functionality to handle. I suggest looking at their full documentation here: tabula-py.readthedocs.io/en/latest/
@@MishaSv ah thanks!! I'll go see if I can figure that out.

Code is running without any error but still not getting teh excel file. Can you help please?
Helloo. Great tutorial. A quick question. If i wanted to use this on my application and host it, will it still work after hosting too
bro while trying to extract the whole pdf , its only giving me the last page excluding all the other pages ....can you help on this
It depends on how the original PDF was created. If it has images of tables inserted then the script might not get it from the PDF. It will only work if the tables were originally created as tables in the PDF.
@@MishaSvIs this going to work if the pdf is scanned 1st using ocr, after that extract all the tables all at once?.
Really great tutorial love this❤❤

You will have to extract the whole table, read it as a DataFrame, and then select the first from it using pandas.
I need to learn coding print replication from pdf to html
I LOVE YOU!
how to handle if a single table is spanning over 2 pages?
Good Videos, but the text is very small. You GOTSTA try zooming in. ;))
can ı use scanned pdf???
I haven't tried using it on scanned PDF files. Feel free to try the same code, and let me know in the comments section if it worked!
How would you change this code so that you only extract a specific column from a table
You can extract the whole table and then just select the column you need using pandas.
