Rename file to custom name after download
Hello! I have recently been having a lot of trouble renaming my file to end with '.csv'. I have to download four different files, then rename each. I am automating a google docs like app which demands that my files end with 'csv'. However when I use suggestedFilename(), it names all of the downloads the same name which ends up getting the files confused even when they are saved to different variables. I tried using an object literal to run something like:
const filePath4 = 4${download4.suggestedFilename()}
This doesn't work either and it keeps giving me the error that this path doesnt exist. Does anyone know how I could rename each a unique name that also ends with 'csv'? Thanks for any help.
This thread is trying to answer question "How can I rename each downloaded file with a unique name that also ends with 'csv'?"

Saving Downloaded Files with Unique Names in Playwright
You can use the saveAs method from Playwright's Download class to rename each downloaded file with a unique name ending in '.csv'. Here's how:
First, start waiting for the download event before clicking the download button.
const downloadPromise = page.waitForEvent('download');
await page.getByText('Download file').click();Once the download event is triggered, get a reference to the Download object.
const download = await downloadPromise;Next, generate a unique name for the downloaded file. Let's assume you have a function generateUniqueName() for this purpose.
const uniqueName = generateUniqueName() + '.csv';Then, specify the path where the download should be saved.
const savePath = 'https://ray.run/path/to/save/download/' + uniqueName;Finally, save the downloaded file with the specified path and name.
await download.saveAs(savePath);And that's it! You've successfully renamed a downloaded file with a unique name ending in '.csv' using Playwright. Remember to always refer to the official Playwright documentation for more detailed information.
