I tried this out - but it looks like the images are squished. In a 600x422 image I tried, the columns were originally .03" in Excel. Adjusting them to .1" seemed to fix the perspective.

I just want to alert people to a bug in this piece of software they'll doubtless be using in mission-critical applications.

Thanks. Up to now I only tested with Libre Office.

The bug is fixed now. ;) You can select the output format via command line.

Last time I came across this idea (2011) a I made my own version that rendered to html. Upload an image, place each pixel's rgb value in a 2d array, send it back to the client as a html table where each cell's background color is set to a pixel's rgb value. It comes out looking blocky and I couldn't figure out why.

Here it is: http://excelimagemaker.apphb.com/

Pretty sure Excel supports copy-pasting a table from the browser directly into Excel so you can do that too and just set each cell's height and width to 1px to see the image in Excel.

Back in the day, one way to 'protect' images online was to table/div-ize them. This is apparently still a thing for email and web ads:

More than 3 colours? This isn't a patch on Matt Parker's RGB spreadsheet maker: http://www.think-maths.co.uk/spreadsheet

No, it uses up to 55 custom colors.

Precisely, 55 is more than 3

This is a cute hack, but why? (Mostly because it doesn't take into consideration using text glyphs _inside_ each cell and a second color to add texture)

Come on, let's go full libaa!

Nowhere, that's the point. :)

wherever we want

Perhaps we should start to use more up-to-date images of her? :) http://www.cs.cmu.edu/~chuck/lennapg/
