JSON, YAML, INI, TOML, XML... these are all serialization and data interchange formats. JSON, and YAML are particularly lightweight for representing datastructures such as hashes, arrays, and nested structures.

Are you committed due to some immutable legacy technical debt to using Perl files to store your data? Could you possibly adopt a more secure, simpler format such as JSON? JSON is popular because it is simple, and if treated as data (ie, not evaled by a Javascript engine as code) is fairly secure, in that it won't be exposing your code to injected code.

Perl supports JSON and YAML quite easily using modules from CPAN, and since Perl 5.14 JSON is even supported in the Perl core distribution via JSON::PP

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 How to display code and escape characters are good places to start.
