Greetings InDesigners,

I am producing a document for my club which started out as a document to be printed I used CMYK colorspace.

Now they want to post it online and email in PDF format.

How do I take an existing CMYK colorspace document and convert it to RGB?

I am new to Indesign and have been told by others that it can't be done. I am looking for a second opinion.

Thank you, any assistance is appreciated.

No, the logic of an INDD document is to keep the original as it is and only modify the output when exporting.
This allows you to export in RGB, CMYK, with or without spot colours, etc., depending on your needs.

Or go to Edit, then Transparency blend space, then you can select RGB or CYMK

InDesign documents don’t have a colorspace—a document or page can have a mix of RGB, Lab, or CMYK colors and swatches, you can also place RGB, Lab, CMYK, or Grayscale images.

You can export a PDF into a single color space via the Output tab. So you might want to convert all CMYK color into a uniform RGB space in case the viewing browser does not color manage CMYK color correctly. So an Output setup like this would convert everything to sRGB. Exporting to an Interactive PDF as JR_Boulay suggests also forces all color into sRGB:
