Layer names from csv
Hi everyone.
I came to you with a problem I’m struggling with. At the beginning I must write that I do not know how to write scripts, all my struggle consists in trying to modify existing ones.
Is it possible to write a script that will rename layers by taking the names from a csv file? In my case i’m working on duplicated precomps with master properties. Every new duplicate of layer takes values from csv, based on layer index. I would like to change the names of layers collectively, based on data from the same csv, only, for example, from column No. 2, where I have the name and surname of the person.
I found two scripts at this forum:
First:
app.project.activeItem.selectedLayers[0].name = "BG"app.project.activeItem.selectedLayers[0].name = "Matte"Second:
crtComp = app.project.activeItem;for (var i=1;i<=crtComp.numLayers;i++){
currentLayer = crtComp.layer(i);
if(currentLayer instanceof TextLayer){
crtComp.layer(i).name = crtComp.layer(i).text.sourceText.value;
}
}both written by Andrei Popa
First one working great, but i can,t modify it to take data from csv and batch working. Second one is changing name of text layers, so if i take values of textsource from csv it works, but only on text layers.

Hi.
This should be the logic of your script:
var myFile = File.openDialog("Choose CSV file..");
var arr = csvToArray(myFile);
var columnIndex = 2;
var comp = app.project.activItem;
for (var i = 1; 1 <= comp.numLayers; i++) {
comp.layer(i).name = arr[i][columnIndex];
}For this to work, you also need the csvToArray function which parses the CSV. You can find it here:
Just paste the code from pastebin under the one from this page.
You may need to change columnIndex to 1.

Hi Andrei.
Thank you for Your answer and help. The script works great, it does exactly what I want. Its action ends with a message “Unable to execute script at line 6. unndefined is not an object”, but apparently that’s not a problem:)
I just have one more question. In line 4 we have “var comp = app.project.activeItem;”. Does this mean that the script should only work on selected layers? At the moment it renames all the layers in the composition I’m currently in. It’s not a problem, but I’m asking more out of curiosity.
Thank You very much, you helped me save a lot of time 🙂

The error is actually a typo I did in the for loop. So the script runs until it finds an error 😀
The for condition should be this one
for (var i = 1; i <= comp.numLayers; i++)
The line 4 gets the composition object corresponding to the composition that is opened in the timeline. We use that in the for, to loop through all its layers.
If you want to only apply this to selected layers, you should replace the for loop (the 3 rows) with this part:
var selLayers = comp.selectedLayers;
for (var i = 0; 1 < selLayers.length; i++) {
selLayers[i].name = arr[i+1][columnIndex];
}Haven’t tested this, but it should work.

Works like a charm 🙂
Thank You for Your help, it will speed up my work. -
Thank you for solving this, Andrei!
