jWorkBook: Get Database information directly into your spreadsheet
Now a quick way to get the information that is currently in your system databases directly into your spreadsheet. jWorkbook is an Excel Add-In that enables you to build powerful queries to access the information directly and see the information in your Excel Spreadsheet. You can build reports quickly and interactively using the power of single or multiple SQL So.... the information you need is stored in the Oracle, Access or SQL database and you need to look at it and do some calcs and write a quick report? What are your options? Simple, find a programmer, tear him or her away from the thousand other jobs on the go and try to explain what you want. They will put your request into a queue and hey presto 3 months later you get the information you want...if you are lucky!
Enter jWorkBook: start up Excel, enter a simple SQL command....bang the information is there!
Not quite what you want? No problem, refine the command and run it again. Or add another command and run them both. Format the output in your spreadsheet, add a chart and you have your data in the format you want in a couple of minutes. Really that simple? You bet.
SQL is by far the most popular database language available today. It is used as the main form of communication by every database of note. It is extraordinarily powerful. But best of all, to do the vast majority of tasks, it is extremely simple. Unlike languages like C or Basic, you can do most of your data retrieval commands in a single statement. It is a fact that if you understand the English-like Select statement, you are probably 99% of the way to being self sufficient in retrieving your data from the database. Granted, as you get proficient in SQL, you will naturally extend your skills to more exotic structures but from day one, you are productive. But don't take our word for it, run through the tutorial and give it a try.

Excel add-in with eleven powerful worksheet functions for 1, 2 and 3 variable lookup and interpolation. Interpolation modes include: closest-value, linear, piecewise parabolic or hyperbolic, cubic spline and polynomial up to 20th order. The functions can also handle tables containing missing and invalid data.
Includes functions to fit polynomial curves through a set of X-Y data points and return a table of polynomial curve coefficients, as well as, determine the best fit polynomial curve.
In case of an error, TriLookup functions can either return a standard Excel error code or a detailed text error message, indicating the nature of the error and pointing to the cause of it.
Includes online help and example workbooks. Requires Microsoft Excel 97, 2000, XP or 2003 (Windows) or Excel 98, 2001 or X (Mac).
TVLOOKUP & TVLKP search a multi column table for the lookup value in the lookup column and return a value from the same row of the return column. Can use interpolation and handle missing values.
THLOOKUP & THLKP search a multi row table for the lookup value in the lookup row and return a value from the same column of the return row. Can use interpolation and handle missing values.
T2LOOKUP & T2LKP search a 2D (X-Y) table for X values in top row and Y values in left column, and return a value from the intersecting row and column. Can use interpolation and handle missing values.
T3LOOKUP & T3LKP search a 3D (X-Y-Z) table for X, Y and Z values. Return a value V(x,y,z) from the intersecting row, column and table. Can use interpolation and handle missing values.
TVPOLYDATA & THPOLYDATA Calculate polynomial curve coefficients up to a specified order (using the least squares method) for the X-Y data points given in a table. Also determine the best fit curve.
TPOLY returns the Y value of a polynomial curve for given a X value, polynomial order and an array of polynomial curve coefficients. It can optionally return the value of a derivative.
