I'm using Extract Form Fields to get data from a PDF. But upon selecting the area where the desired text is located, the "Value" text area in the popup should be automatically populated with desired text, but that isn't the case. The "Value" field is staying blank.
Any idea what might be causing this?
you need to check whether your PDF has handwritten content or it is a scanned file.
if your PDF does not satisfy above criteria you can easily automate your PDF using Automation anywhere by selecting the area. if your PDF is invoice or bill or any type of GST forms better to use IQ Bot.

I have a fillable PDF. I would like to know the names of the fields in it. I know I can find this out using pdftk and the dump_data_fields flag. However, it is a painful process to match the fieldname to the actual field in the PDF.
Is there a tool out there that shows the real PDF and the fieldnames over it?
When Adobe Acrobat Pro is put into Form Authoring mode, it will show the form fields with their name overlayed.
I'm using pdftk to fill in the form with the generated fdf.
In the PDF form, the form field is configured as a number field with 2 decimal point, and the negative value will be showing with parentheses, for example, -4444 will become (4444.00)
Using any PDF viewers and changing the value on form did make the form display the value correctly with the behaviour explained above (negative value will become value with parentheses)
Tested also with the FDF (by importing to the form), the negative value will be displayed correctly as well.
But when using the pdftk fill-form action, the negative value remains as it is without changing the display, which is still showing -4444 and not (4444.00)
Is anyone experienced this before / has a solution for this?
Update #1
I've also tested Apache PDFBox, it has the same issue :(
And now I'm trying to achieve this by using the PDF's javascript, any clue that this way will works?
Update #2
came across this thread How to refresh Formatting on Non-Calculated field and refresh Calculated fields in Fillable PDF form and so gave it a try with iText as well. However still unable to make it works
Finally, i've found some ways to get the formatting works in the PDF form fields.
Approach #1
Requirements
pdftk
PDF form with javascript
In the PDF, create a "Document Javascript" (see how) and re-assign the form's value to make it dirty as mentioned by Denis in the thread of Update #2. The script could be as simple as below:
var text1 = this.getField('text1');
text1.value = text1.value;
Downside
Javascript will only be triggered when you open the PDF, and if you would like to set the PDF with some ownerPassword to prevent user edit the file, the javascript will just failed because of read-only form fields. Otherwise, imagine you have 100 form fields in the PDF, re-assign each of them is a nightmare.
Approach #2
iText
PDF form
I personally will prefer this approach. The powerful iText already has the API to set the form field and at the same time formatting the field display (see how). The generated PDF is ready to print as well with the correct format.
Downside
Either using the iText API to find out the existing format of the form field, or you will hard code the format in your codes. Require more efforts than using the pdftk.
I'm using a simpler version of ChinKang's #1.
In Tools -> Document Javascripts:
this.calculateNow();
One thing to check is in Tools -> Set field calculation order that any calculations are ordered appropriately.
I then use https://github.com/ccnmtl/fdfgen and pdftk to fill the forms in.
The only gotcha is that you cannot flatten the PDF
I have a visual basic program that extracts text from a PDF and imports the text into excel. It relies on reading the text like a human, reading left to right across the page. However, there are instances on this particular PDF where if I go to select the text with my mouse, I click and drag straight across but Adobe starts to select/highlight words on the above and below lines before continuing to highlight across the page. This gives me data that I do not want/need. The page has renderable text and is not from a scanned document.
Is there a way to "reset" the way Adobe interprets the text on the PDF? Since the information on the left is far from the information on the right, it treats them almost like separate columns.
I've tried saving the PDF in different formats such as a txt or postscript and distilling to another PDF but they all seem to result in the same outcome. This is weird to me because I have other similar PDFs where this isn't an issue.
Any help or thoughts would be greatly appreciated, thanks.
As PDF (in its basic form) essentially means placing strings on a canvas, the concept of "sentence" or "reading order" is not built in.
In order to extract text, you would have to read out the bounding box of the piece of text, and then use some logic and heuristics to assemble your text based on the coordinates of the bounding box.
Things can be easier if the PDF is a structured PDF, where the text contents is embedded as text in the document. This is also the prime requirement for an accessible document. So, if your document is accessible, you can rely on the structure for the correct reading order.
I receive around 30 workorders a day from my primary client. They send them to me in a standardized report format, in a single PDF, with one page for each different workorder. Unfortunately, these PDF reports dont include the workrorder_ID in a barcoded format, only in regular text font and they are unwilling to comply to my request to modify the report by adding a barcode. Is there a way to automatically add a barcode to the PDF? basically I would want the PDF editing app to search for the text “workoder ID:” and to insert the barcode, beneath the work_order ID.
please advise. thanks very much
You will need to use a PDF Library that includes a text extraction that includes reporting the location of each string extracted. When you find the location of the Work Order ID text you can then use the same library add the barcode in correct position. Quick PDF Library would be one option and iText be another.

I'm trying to build a web app to programmatically fill out a PDF form. I am going to configure my form first in Adobe Acrobat, then write a Java app with iText to fill out all the form fields via user input from the web. The base form I need to fill out comes from the US government. They created form fields with extremely large kerning (character spacing) values I need to change. However, there appears to be no way to modify this value in the Acrobat UI.
Does anyone know how to manipulate character spacing on form fields in Acrobat 8.0 for Windows? I could try to use iText to programmatically manipulate the kerning of the original document, but this would be much more tedious.
I believe I figured this out: kerning is called "combing" in acrobat, and each of the form fields have been "combed". The strange thing is this option isn't checked when I view the properties of the form field, but "combing" is the behaviour I was attempting to replicate.
