Without knowing what OS you are using & what tools you have installed, I am suggesting these very general online tools which can be used manually :
(1) https://convertio.co/csv-pdf/
(2) https://cloudconvert.com/csv-to-pdf
(3) https://www.beautifyconverter.com/tsv-to-pdf-converter.php
(4) https://wtools.io/convert-tsv-to-pdf
In case you want to automate this, eg to generate every week or every month, you might want to specify what OS & tools you are going to use.
On Windows (& Mac) with MS Excel, it is very easy to manually or automatically "EXPORT" to various formats including PDF.
With Free Office Suites, you can achieve that on all common Platforms including Linux.

Let me transfer comments into an answer, just to make it a little more permanent…
On Mac you can 'print' anything directly to PDF; it's built-in at system level.
As a test I grabbed a sample csv file online to see exactly what would happen. Mac has a built-in 'reader' for a lot of file types. You just select the file & hit the spacebar & it will show you what it looks like [Quicklook]. Above that is what happens if I make it open in a text reader, which is to be expected. The formatting on Quicklook wouldn't win any prizes for beauty, but it's accurate & it picked a decent, legible font. This is what it would print with no further editing. I honestly don't think it's a bad attempt.

Just as an experiment, I told the Mac to just 'print the file' [literally select the file in Finder (like 'Explorer'), then Cmd/P with no other intervention]. It launched Numbers [which is the macOS equivalent of Excel], sent the print job then closed it again. This is a screenshot, of a scan … of the print. It auto-generated the bold & header demarcation without me asking. Even better than the Quicklook version, imo. The print itself is sharper than the scan, of course.

So this is what the Mac will do to a 'plain' csv file, with no other user intervention.
This is a cleaner screenshot, from Numbers

Once you have your shiny new layout, you can turn it into a pdf in the same way as any file on the Mac - Open the Print dialog, Cmd ⌘ P , then bottom left, PDF > Save as PDF…

Does your CSV to PDF converter work on mobile?
I have a CSV file that contains multiple contacts and i want to convert this file into PDF file. I tried many ways but its not working. I want to get the best solution to convert CSV file to PDF on Mac ?
Part of my job involves having to fill out a pre made PDF form with data that I export from our software to a CSV file. Sometimes there can be 50 plus lines of data I have to manually copy and paste line by line. I've tried copying the whole column to paste into the whole column on the PDF, but it doesnt work.
Is there a tool that exists to accomplish this task out there already? If one doesn't exist, where I do start in terms of programing languages to build said tool?
