I have a list of numbers throughout my document
I want to grep find only numbers that are only 1 to 3 digits. I am just a beginner in indesign and I have started writing greps but this looks tricky.
I found a similar query here Grep Doubt and i guess the below query should help you out too. I have modified it only a bit to suit your need.
This would find all numbers in your documents that have one, two or three digits. This will also include numbers like 00 and 000(based on digits, YES it should)
Exactly what I needed. I got that.
