The 5 Crucial PDF & Office Features For Corporate Apps in Pure Go

Most of the times, developers lack the foresight to determine the type of functionalities required by their clients. This causes delays and budget issues, but it doesn’t have to be like that. We will discuss what corporate clients usually require and whether it is wise to resort to inhouse development.

The greatest pain of Golang developers when building corporate applications, is how to work with PDF and office files. Working with PDF files is especially troubling since manipulating them requires you to have an in-depth understanding of the PDF format and how it works with images and other content.

Completing a task as mundane as placing a table at the right place on a PDF file can take hours when it should only take a few minutes. Anyone who has ever worked with PDF has gone through these troubles. This is where UniDoc’s pure Golang libraries come into play, which has been developing pure golang libraries since 2016 and provides an easier alternative to work with PDF and other office documents.

UniDoc Libraries

UniDoc has been active since 2016 and since the last four years, we’ve worked on improving the library’s speed, security and features. We listen to the customers and continuously update the library to match their requirements.

UniPDF and UniOffice are the two main products of UniDoc library, where the former is focused on working with PDFs and the latter allows you to work with word, excel and presentation files.

Using UniPDF, you can create new PDF reports, extract content such as images and text from old ones. You can also compress your PDF documents, secure them by creating digital signatures and automate your office tasks by using these features. We’ve recently introduced JBIG2 encoding support in UniPDF. This will allow you to further optimize your PDF reports by reducing the size of black and white images by up to 90%.

Using UniOffice, you can use the power of pure Golang to automate office tasks such as creating template letters. You can create new excel sheets, extract data from existing ones and work seamlessly with presentation files.

Playground Examples

It’s best to let the code speak for itself. To make it easier for developers to try out the power of UniDoc, we’ve set up a playground. You can quickly write code, run it and view the results without having to setup an environment on your local computer.

All you need is a smart device, a browser and a concept, which the playground will allow you to implement quickly. In the upcoming sections, we’ll share some examples from UniPDF and UniOffice.
