How can I extract a value from this simple JSON string in Excel VBA? -


i have simple json string in vba : 

{     price_a: "0.172",     price_b: "0.8",     price_c: "1.3515" }

i extract value of price_a 0.172.

how can done in excel vba? using microsoft office 2013.

i don't need extensive json library. simple function extract value of price_a.

a regexp gives more control on parsing rather relying on character length.

as example:

sub test_function() dim strin string  strin = "{" & _     "price_a: " & chr(34) & "0.182" & chr(34) & "," & _     "price_b: " & chr(34) & "0.8" & chr(34) & "," & _     "price_c: " & chr(34) & "1.3515" & chr(34) & "}"  msgbox get_value(strin)  end sub

extract first set of numbers in "" after price a. can adapted check price b

public function get_value(strin string) string   dim objregexp object dim objregmc object set objregexp = createobject("vbscript.regexp") objregexp     .pattern = "price_a: ""([\d\.]+)"""     if .test(strin)         set objregmc = .execute(strin)         get_value = objregmc(0).submatches(0)     end if end end function

shorted version extract first set of numbers

public function get_value(strin string) string dim objregexp object set objregexp = createobject("vbscript.regexp") objregexp     .pattern = "[\d\.]+"     if .test(strin) get_value = .execute(strin)(0) end end function
