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-Find , it 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.
Due to the CSP, an Excel file can't be decrypted, and thus the password to open can't be removed, though the brute-force attack speed remains quite high. The situation changed fundamentally in Excel , where 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 Excel , the 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. Microsoft Excel Viewer Microsoft Excel Viewer was a freeware program for viewing and printing spreadsheet documents created by Excel.
Excel Viewer is similar to Microsoft Word Viewer in functionality. There is not a current version for the Mac. Numeric precision Main article: Numeric precision in Microsoft Excel Excel maintains 15 figures in its numbers, but they are not always accurate: the bottom line should be the same as the top line.
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 function , as 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.
In the second line, the number one is added to the fraction, and again Excel displays only 15 figures. In the third line, one is subtracted from the sum using Excel. Because the sum in the second line has only eleven 1's after the decimal, the difference when 1 is subtracted from this displayed value is three 0's followed by a string of eleven 1's. However, the difference reported by Excel in the third line is three 0's followed by a string of thirteen 1's and two extra erroneous digits.
This is because Excel calculates with about half a digit more than it displays. Excel works with a modified version of the IEEE specification. See the main article for details. Besides accuracy in user computations, the question of accuracy in Excel-provided functions may be raised.

Particularly in the arena of statistical functions, Excel has been criticized for sacrificing accuracy for speed of calculation. Microsoft has announced some of these issues are addressed in Excel In the case of excessively large results, Excel will return the error warning NUM!
