Just rename the file with a .js extension and assign the array to a variable.
For example if your file is this kind of thing
[ {someKey:[{anotherKey: data}]}, {someKey:[{anotherKey: data}]}, {someKey:[{anotherKey: data}]}, {someKey:[{anotherKey: data}]}, ... ]Do this
namespace Lut { const pcs = [ {someKey:[{anotherKey: data}]}, {someKey:[{anotherKey: data}]}, {someKey:[{anotherKey: data}]}, {someKey:[{anotherKey: data}]}, ... ] }Then you can access it using Lut.pcs
