Pasting keyframe data on multiple layer using script

As we know, in after effects, we can copy multiple keyframes from one layer (ctr + C) and just paste on another (ctr + V) to get the animation copied as it is on the new layer

Now I already have the copied keyframe data with me -

Adobe After Effects 8.0 Keyframe Data

Units Per Second 30
Source Width 1920
Source Height 1080
Source Pixel Aspect Ratio 1
Comp Pixel Aspect Ratio 1

Transform X Position
Frame
0 271
4 271
20 960
54 960
70 1720

Transform Opacity
Frame percent
0 0
4 0
20 100
54 100
70 20

End of Keyframe Data

Can I store this in a variable and then bulk-paste it on multiple layers using a script?
