Managing Word Documents With Spire.Doc Library Functions

A few days ago, one of my readers emailed me asking for help with some functions in the Spire.Doc library. In this post I explain various Spire.Doc Library Functions that eases the life of a developer.

For beginners, you can download the Spire.Doc library from here. The best part of the library is that it is an independent Word .NET component and doesn’t require Microsoft Word to be installed on the machine. Spire.Doc is present in Free as well as Paid edition. You can use the free version for reading/writing 100 paragraphs and 5 tables only. If your content is more than this, you will need to purchase the paid version.

Let’s get started with the library. We’ll use this Word file for our examples. A screenshot below,


Modify an Existing Word Document:

This library divides the Word document into paragraphs & sections. In the screenshot above, you see 4 headings and 4 paragraphs. When we read this document using the library, we get 8 paragraphs. The below code will add some text to the 1st heading & 1st paragraph of the code.

In the code above, we load the file using LoadFromFile() function on Line 2. On Line 4 & 5, we get references to the 1st heading and the 1st paragraphs. On Line 7 & 8, we append text to the existing paragraphs and finally save it on Line 10 to a new file. It is important to provide the format of the file being saved. There are various options provided by the library such as Doc, Docx, Doc2010, Doc2013, PDF etc. Below is a screenshot of the edited file.

NOTE:

You would see an Evaluation warning with the trial version. This warning will go as soon as you purchase the licensed version. If you want to purchase it, you can do so from here.
