I think you sort of answered your question there already. You just do it and catch the errors. No errors: valid, proceed. Errors... you decide what happens next. E.g.-

use warnings; use strict; use JSON::XS; use Try::Tiny; my %json = ( empty_obj => "{}", empty_array => "[]", bare_string => "hai", obj => qq|{"o":"hai"}|, bad_obj => qq|{o:hai}|, ); for my $name ( keys %json ) { printf "%11s --> ", $name; try { my $throw_away = decode_json($json{$name}); print "OK!\n"; } catch { print "Error: $_"; }; } __END__ obj --> OK! bare_string --> Error: malformed JSON string, neither array, object, n +umber, string or atom, at character offset 0 (before "hai") at ... empty_obj --> OK! bad_obj --> Error: '"' expected, at character offset 1 (before "o: +hai}") at ... empty_array --> OK!

Use:  <p> text here (a paragraph) </p>
and:  <code> code here </code>
to format your post; it's "PerlMonks-approved HTML":

  • Are you posting in the right place? Check out Where do I post X? to know for sure.
  • Posts may use any of the Perl Monks Approved HTML tags. Currently these include the following:
    <code> <a> <b> <big> <blockquote> <br /> <dd> <dl> <dt> <em> <font> <h1> <h2> <h3> <h4> <h5> <h6> <hr /> <i> <li> <nbsp> <ol> <p> <small> <strike> <strong> <sub> <sup> <table> <td> <th> <tr> <tt> <u> <ul>
  • Snippets of code should be wrapped in <code> tags not <pre> tags. In fact, <pre> tags should generally be avoided. If they must be used, extreme care should be taken to ensure that their contents do not have long lines (<70 chars), in order to prevent horizontal scrolling (and possible janitor intervention).
  • Want more info? How to link or or How to display code and escape characters are good places to start.
