PDFInjector

PDFInjector is a commandline utility that takes a PDF file and JSON data as input, and generates a new PDF, filling its forms with the data from the JSON. The new PDF is saved to the output directory specified by -o along with summary.txt which shows the fields that were successfully filled.

Usage

Clone the project and compile it into a jar OR download the jar directly from the releases page.
run with java -jar pdfinjector.jar -h to show a list of flags.

-d Data. Either in JSON format, or the path to a json file.

Example

Filling out the fields with their names. $ java -jar pdfinjector.jar -i /path/to/document.pdf -o /path/to/destination/output.pdf -p
Filling out the fields from a json file

$ java -jar pdfinjector.jar -i /path/to/document.pdf -o /path/to/destination/output.pdf -d /path/to/data.json

Filling out the fields from direct json data

$ java -jar pdfinjector.jar -i /path/to/document.pdf -o /path/to/destination/output.pdf -d {\"fields\":[{\"key\":\"name-field\",\"value\":\"John Doe\"}]}

      "value":"John Doe"
    }
  ]
