Splitting string to array based on string length (amount of characters)

[OPK]

Hi. Looks easy enough, but I've been unable to make this work. Some apps eg Google Translate, Twitter, SMS etc only allow a max amount of characters being entered. So how do I split a 500 characters string into chunks of maximal 200 characters, while keeping the last word intact?
I'm thinking
- use Regex to find last space before every 200th char
- Replace it with π
- Use split to array with π as delimiter
But none of the Regex formula's I found seems to work well...

As said, I found several suggestions which, I couldn't get to work:
• ^\s*(?: (\S{200})|([\s\S]{1,200})(?!\S)) ->no space between ":" and ":" but if I delete that, it will show a smilie...
• .{1,200}\w*+

.{1,200}\s is working fine on Regex 101 site; it is working fine in Extract Text + First Match, but it is not working in Remove Text (bug?) and as there is no First Match option; it is not the result I need...

Something like the attached -- using a regular expression to pick off 200-character chunks at a time, appending each to an array, and doing a straight (non-regex) match for the Remove Text action?

BIG thanks RSF, you did in 10 statements, what I did in 46; your macro is almost correct, as it misses the last chunk. It is however present in the str var, so I added one statement and now it is perfect.


Problem solved
Thanks again!

Ah, I see what's happening. Good catch. The issue arises due to the regular expression looking for a space (\s) after each chunk. My test string had a space at the end, so it worked without that extra action at the end; your version works perfectly for input strings with or without a trailing space, although it may end up with an unnecessarily-short final chunk.

An alternative would be to edit the initial action that assigns the AllText variable to the str variable, to append a space:

Then the original loop works OK, without that additional chunk assignment at the end...
