Certain programs also exist that compare changes made to objects like JPEG, TIFF, BMP, PNG images embedded in documents, and plain text files.
"[1] With the advent of personal computers and the ubiquity of word processing software, the need arose to find a way to manage changes made to document versions shared via disk, and later email.
In many cases, not enough due diligence on the software’s part was conducted; users would not be informed of sections that were not successfully compared.
However, later software (especially Microsoft Word) enabled multiple types of information to be presented in a single document.
The majority of document comparison software programs have not yet included mechanisms to mitigate the risk related to changes inside of embedded objects.
The software program that can compare changes made in embedded objects provides pixel-to-pixel comparison of images and cell-level comparison of embedded Excel spreadsheets and other changes made to these complex, compound documents.
As the documents constructed in this business vertical may be binding on either side's clients, it is essential that the risks associated with changes are completely mitigated.
Professionals in the banking, finance and accounting industries manage large amounts of data in spreadsheets.
As one change to a value or formula could affect a substantial amount of data, these professionals find document comparison (such as comparison of two versions of a MS Excel spreadsheet) to be extremely useful in assuring accuracy in document change management.
