pdfforms is a small utility for populating fillable pdf forms from a csv data source. It was created with the intent of filling US tax forms using tax data prepared with a spreadsheet, but should be equally applicable to other forms.
- Assigns numeric id for each field
- Generates test pdf showing ids of text fields
- Merges csv data into final filled pdf
- Can process multiple pdfs at a time
pdfforms requires Python 3.5 or higher and pdftk, which does all the real work.
To install: pip install pdfforms
Let's say you have a spreadsheet with your tax calculations. You want to populate your tax forms with the data from the spreadsheet. pdfforms allows you to do so with the following steps:
First pdfforms must inspect the forms to be filled. pdfforms will extract a list of fields in each of the specified documents. Each field is assigned a numeric id, and test documents are generated with filled forms, showing the id of each text field:
$ pdfforms inspect f1040*.pdf f1040sse.pdf f1040sce.pdf f1040.pdf
The filled test pdfs are stored by default in the
test/subdirectory.Browse the test pdf files and add the field numbers of the fields you need to fill to your spreadsheet. pdfforms only reads the first and third columns of the datafile. The first column should contain the name of the pdf file with the form to fill and the field numbers. The third column should contain the data to be written into the field. The rest of the sheet is ignored, so you can use it for notes, calculations, etc.
Below is an example spreadsheet for a (fictional) 2016 tax return.

The test pdfs do not show field numbers for checkboxes. Currently the only way to fill checkboxes is to examine the
fields.jsonfile and find the field number and allowed values of the checkbox.Once the file name and field numbers have been added to your spreadsheet, save the spreadsheet as a csv file and fill the forms:
$ pdfforms fill mydata.csv f1040sse.pdf f1040sce.pdf f1040.pdf
The final, populated pdf files are saved by default to the
filled/subdirectory.
