    GREP is a foreign language to me…please help!

    Have a document of all numbers, no spaces (1 billion digits of Pi) and now need to add a space every 7th number. How would I do that?

    Thanks in advance!

    Needs to look like this:

    Hi Jennifer,
    try to search:
    (\d\.\d{7})(\d{7})(\d{7})(\d{7})(\d{7})(\d{7})(\d{7})(\d{7})(\d{7,})
    replace with:
    $1 $2 $3 $4 $5 $6 $7 $8 $9

    Unfortunately you cannot add the space into more than 9 groups of numbers, so you need to perform a second search and replace for the last group
    search:
    (\d{7})(\d{7})
    replace:
    $1 $2

    Thanks Claudio – so do you mean that it will only do 9 groups of 7 at a time? I have 1 billion digits of Pi!

    You have only 9 variables so can separate a maximum of 9 groups

    repeat this search:
    (\d{7})(\d{7})(\d{7})(\d{7})(\d{7})(\d{7})(\d{7})(\d{7})(\d{7,})

    and replace with:
    $1 $2 $3 $4 $5 $6 $7 $8 $9

    as many time as the number is over.

    Maybe someone here has a different solution.

    OK, wait… why on earth would you need to put a space between every 7th digit? Not every 10th digit? What mathematical planet are you from? ;-)

    And why pi?! (You may or may not know that the co-host of this web site — me — is also a pi fanatic.)

    Here’s one solution: In the find/change dialog box, choose the GREP tab. Then search for (\d{7}) and replace it with $0

    Then click Change All. That will insert a space after every 7th digit.

    David, you’re right!
    You saved Jennifer’s life :)

    I think that you don’t need the parenthesis () in the search filed, \d{7} should be fine.

    Oh beautiful!! Will try that. Thanks to both of you.

    It’s for a client – I believe trying to memorize 1 billion digits of Pi?? Thinks if grouped like phone numbers will be easier to memorize? Mine is not to question, only to provide the results he wants! Lol.

    Ah! Yes, that actually does make sense. But all the record-holders in pi-memorization are Asian… I believe it is far easier to memorize digits in Chinese and Japanese. I talk about that in my book The Joy of Pi. Good luck to your client, and to you! :-)

    OMG…..not going to believe this…..but now client wants me to put it in groupings like actual phone numbers of 3 and then 4 digits:

    3.141 5926 535 8979 323 8462 643 3832 795 0288 419 7169 399 3751 058 2097 494 4592 307 8164

    Ready to pull my hair out….
    What would the GREP be for that???? Is it even possible??

    Jennifer, you can leave you hair in place…

    Try search for (\d{3})(\d{4}) and replace with $1$2
