Our New Web Based Whitespace Trimming Tools

Friday, October 29th, 2010

We added a couple new tools to Web Tools by Perceptus today.  We also cleaned up the look of the site a little – it’s gone all the way from ugly to almost passable.  Similar to our blog, over time, the trickle of traffic to our web based text mangling site has grown, and it had earned a bit of our effort to tidy it up. Who knows, if this keeps up, we’ll have to keep adding more tools!

The new tools?

  • The Whitespace Trimmer – Paste a blob of text. Every line  of text will be trimmed of spaces on the left and right and returned to you.
  • The Blank Line Remover – Paste a blob of text.  Every blank line will be removed.

Like the rest of the site, the clipboard is your friend.  Run one tool.  Copy the result to the clipboard, and run another one of our tools on the result.



The Fastest Way to Lookup Multiple Historical CAD to USD Rates

Friday, August 21st, 2009

At Perceptus, we deal with the Canadian Dollar to US Dollar exchange rate a lot.  Doesn’t every small business in Canada? We need to convert our US revenues to Canadian CAD amounts for tax purposes, among other things.

We used to use the common websites like or to get our historical exchange rates.  But those sites are too slow if you need to look up a half a dozen exchange rates from the past.  It takes several clicks to retrieve a single exchange rate for a date in the past.

So, I went looking for something better to use.  In fact, I was prepared to create a new tool for looking up historical Canada to USA exchange rates on the Web Tools by Perceptus site if I couldn’t find a satisfactory alternative.

Unfortunately for, I did find a reasonably good way to get a lot of old exchange rates in an efficient way.  The IMF website, of all places, has a great custom table generator.

Here’s the link: Http://

However, this link (until it breaks, anyway) will take you directly to every CAD to USD rate in the last 365 days in a nice and tidy table.  Just generate the table, and look up the rate you need for the date you need.
