Dear Sir, In case there are atleast 80 files or more having same format containing datas in columns in each file with different figures, I want to merge all file in a single sheet in one shot. Kindly...


If the column names and orders are same across files, then you can directly use the MS Excel's import data function, this will do your job.

Alternatively, if you want to do it manually, import each file in separate excel worksheet using data import wizard or simple copy paste of data (in latter case you have to use Text-to-Col feature of excel), and then manually append all figures (copy-paste in one go) to any external excel sheet.

Then finally, export/save as that external sheet to any filename of your choice.

Hope this helps.

Excel formula

I'm assuming you'd like to assign a numerical value to cardinal references (1st, 2nd, 3rd, 4th, etc.).

Best way to do this is to create a quick lookup table on a separate sheet of the same .xls document. Down at the bottom of the page, click on Sheet2 and create a quick table where column A has 1st, 2nd, 3rd, etc. and column B has your values.

Now click back to Sheet1 where your data is and in A2 put this formula:
=VLookup(A1, Sheet2!$A$1:$B$x, 2, FALSE)
Note: replace the lower case x in the formula above with the number of the last row of data in your lookup table on Sheet2.

You can copy and paste this formula down the column to calculate your other values.

Hope that helps!

Selecting only Numeric part of a database feild

Well, one solution is to fetch the whole data, including the non-numeric part, and then convert that into a number. Most programming languages strips off the non-numeric part of a string when converting into a number. For example, converting '24Michell' to a number will result into '24'. Consult your programming manual on how to convert a string into a number.

I have data in excel

Excel cannot search by colour, however you can rank by adding a column, in which you place a ranking value (if you colour code as well you can appear to rank by colour), sorting by the ranking column will give you the same ranked rows together in numerical order.
