This may take on the form of "embedding" where an application uses another to handle a task that it is more suited to, for example a PowerPoint presentation may be embedded in an Excel spreadsheet or vice versa.
Excel can accept data in real time through several programming interfaces, which allow it to communicate with many data sources such as Bloomberg and Reuters through addins such as Power Plus Pro. Although it is easy for users to create such links, programming such links reliably is so difficult that Microsoft, the creators of the system, officially refer to it as "the protocol from hell".
Network DDE Extended the protocol to allow spreadsheets on different computers to exchange data. Starting with Windows Vista, Microsoft no longer supports the facility.
RTD although in many ways technically superior to DDE, has been slow to gain acceptance, since it requires non-trivial programming skills, and when first released was neither adequately documented nor supported by the major data vendors.

Password protection Microsoft Excel protection offers several types of passwords: Password to open a document  Password to modify a document  Password to unprotect worksheet Password to protect workbook Password to protect the sharing workbook  All passwords except password to open a document can be removed instantly regardless of Microsoft Excel version used to create the document.
These types of passwords are used primarily for shared work on a document. The only type of password that can prevent a trespasser from gaining access to a document is password to open a document. The cryptographic strength of this kind of protection depends strongly on the Microsoft Excel version that was used to create the document.
In Microsoft Excel 95 and earlier versions, password to open is converted to a bit key that can be instantly cracked. As regards services which use rainbow tables e.
Password-Findit takes up to several seconds to remove protection. In addition, password-cracking programs can brute-force attack passwords at a rate of hundreds of thousands of passwords a second, which not only lets them decrypt a document, but also find the original password.
The situation changed fundamentally in Excelwhere the modern AES algorithm with a key of bits started being used for decryption, and a 50,fold use of the hash function SHA1 reduced the speed of brute-force attacks down to hundreds of passwords per second.
In Excelthe strength of the protection by the default was increased two times due to the use of a ,fold SHA1 to convert a password to a key.

A similar problem occurs when a text happens to be in the form of a floating point notation of a number. In these cases the original exact text cannot be recovered from the result.
In the case of entering gene names this is a well known problem in the analysis of DNAfor example in bioinformatics. The problem was first described in You cannot open two documents with the same name, even if the documents are in different folders.
To open the second document, either close the document that is currently open, or rename one of the documents. Numeric precision in Microsoft Excel Excel maintains 15 figures in its numbers, but they are not always accurate: Despite the use of figure precision, Excel can display many more figures up to thirty upon user request.
But the displayed figures are not those actually used in its computations, and so, for example, the difference of two numbers may differ from the difference of their displayed values. Although such departures are usually beyond the 15th decimal, exceptions do occur, especially for very large or very small numbers.
Serious errors can occur if decisions are made based upon automated comparisons of numbers for example, using the Excel If functionas equality of two numbers can be unpredictable. Although this number has a decimal representation that is an infinite string of ones, Excel displays only the leading 15 figures.You are trying to open an Excel file and you get: “File in Use: File is locked for editing by another user.” Sometimes the file is locked by another user, and other times the "another user" is actually you.
