Doubtless there are more sophisticated ways to do this, but for a quick one-off, manual validation test on tabular data presented by a web page, I scrape it (highlight it) off the web page, hit ^C, paste to a text editor, do some reformatting, then paste to an empty sheet. Then I do my checksums of the page's presentation in the sheet. Find a bug, go to the SQL in the back end, fix the cause, write a little (manually run) SQL validation test test for that case, then cycle through it all again until the bugs are out and a nice little suite of validation tests in SQL. Really nice to have Excel, where I can point-and-click to write sums.
