YAML equivalent of array of objects in JSON

Question

I have a JSON array of objects that I m trying to convert to YAML      AAPL              shares   -75 088       date    11 27 2015                shares   75 088       date    11 26 2015            Is there an equivalent representation in YAML that isn t just JSON  I d like to do something like  AAPL    -       shares  -75 088     date  11 27 2015   -       shares  75 088     date  11 26 2015   but the cleanest thing I ve come up with is  AAPL    -       shares  -75 088      date  11 27 2015             shares  75 088      date  11 26 2015

Great answer above  Another way is to use the great yaml jq wrapper tool  yq at https   github com kislyuk yq  Save your JSON example to a file  say ex json and then  yq -y     ex json  AAPL  - shares  -75 088   date  11 27 2015 - shares  75 088   date  11 26 2015

TL DR  You want this   AAPL    - shares  -75 088     date  11 27 2015   - shares  75 088     date  11 26 2015   Mappings  The YAML equivalent of a JSON object is a mapping  which looks like these     flow style   foo  1  bar  2         block style foo  1 bar  2   Note that the first characters of the keys in a block mapping must be in the same column  To demonstrate     OK    foo  1    bar  2       Parse error    foo  1     bar  2   Sequences  The equivalent of a JSON array in YAML is a sequence  which looks like either of these  which are equivalent      flow style   foo bar  baz         block style - foo bar - baz   In a block sequence the -s must be in the same column   JSON to YAML  Let s turn your JSON into YAML  Here s your JSON     AAPL              shares   -75 088       date    11 27 2015                shares   75 088       date    11 26 2015            As a point of trivia  YAML is a superset of JSON  so the above is already valid YAML   but let s actually use YAML s features to make this prettier   Starting from the inside out  we have objects that look like this        shares   -75 088     date    11 27 2015      The equivalent YAML mapping is   shares  -75 088 date  11 27 2015   We have two of these in an array  sequence    - shares  -75 088   date  11 27 2015 - shares  75 088   date  11 26 2015   Note how the -s line up and the first characters of the mapping keys line up   Finally  this sequence is itself a value in a mapping with the key AAPL   AAPL    - shares  -75 088     date  11 27 2015   - shares  75 088     date  11 26 2015   Parsing this and converting it back to JSON yields the expected result        AAPL                  date    11 27 2015           shares   -75 088                      date    11 26 2015           shares   75 088               You can see it  and edit it interactively  here
