API Spotlight: Split Documents into Separate Files
2/24/2023 - Brian O'Neill

While document merging can help optimize content for short-term presentation or printing needs, it’s rarely to our advantage having large multipage files lying around in storage. For one thing, large files are more difficult to share across most networks, and for another - depending on the industry these files are used in – they can represent a violation of compliance requirements (which may compel a company to separate sensitive data to reduce the risk and impact of data breach).

Document splitting and merging are similar in one respect – they are both time-consuming manual processes which benefit immensely from API automation. The Cloudmersive Convert API makes it easy to implement secure document splitting services into your file processing applications with minimal code, greatly reducing the burden of manual file processing. Below, we’ll highlight a few of our most popular Split Document API iterations.

Split Word DOCX Document into Separate Documents by Page

Microsoft Word (DOCX) is widely used and depended upon for creating and storing specially formatted, rich-text documents, including anything from legal contracts to questionnaires.

The Split Word DOCX API iteration is designed to automatically split an input DOCX file into separate documents – exactly one per page – and return each result alongside its corresponding page number. The API response will contain both a document URL and a DOCX file encoding string for each document, unless a “returnDocumentContents” Boolean is specified in the request to return only a file URL.

Split Excel XLSX into Separate Worksheets

Boasting more than a billion unique users worldwide, it’s no exaggeration to say that much of the business world depends on Excel to organize and model their data.

Since XLSX spreadsheets break down the contents of each individual spreadsheet into worksheets rather than pages, the Split Excel XLSX API iteration returns each new file’s encoding relative to the name of its corresponding worksheet name and worksheet number. To return only a URL, you may set the “returnDocumentContents” boolean in your request to “false.”

Split PowerPoint Presentation PPTX into Separate Slides

While PowerPoint is chiefly depended upon to format and organize digital presentations, its real-world uses often exceed those parameters. For example, it’s common to use PowerPoint slides to create logos, video thumbnails, animations, storyboards, and much more.

The Split PowerPoint PPTX API iteration returns one new PPTX file per slide of your original PPTX document, making it easy to separate and quickly build upon specific slide information or designs. The presentation contents and URL for each slide will be returned relative to slide number, and as with previous examples in this article, the “returnDocumentContents” Boolean may be set to “false” to return only a URL.

Split PDF into Separate PDF Files

Given the universal interoperability of PDF format, it’s common that multi-page DOCX, XLSX or PPTX documents are exported and shared as PDF documents. With that in mind, a PDF splitting operation effectively doubles as a DOCX, XLSX and PPTX splitting operation, ensuring the contents of each document type (and many additional document types not listed here) can convert back into their original format when the need arises.

The Split PDF Document API iteration cleanly divides an input PDF document into one new file per page, returning file encoding which can easily transition back into its original file format through a simple document conversion operation (unless the PDF document is rasterized). As highlighted in the prior API descriptions, you may elect to return only a PDF URL by setting the “returnDocumentContents” Boolean to “false”.
