CSV to PDF is a free browser tool that turns spreadsheet exports into printable PDF tables. It runs entirely on your device — the file is parsed, laid out and rendered inside the browser tab, and no copy of it is sent anywhere. There's no account, no watermark and no upload step.
This page is here because you're about to feed a spreadsheet to a website you've never heard of, and you're entitled to know who runs it.
I'm Stanislav Mashkin, an independent software developer. I build and maintain this converter on my own — there's no team, no investors and no growth target attached to it. It's one of a small set of single-purpose browser tools I run, all built on the same principle: if the work can happen on your machine, it should.
The tools are published under STANMASH LTD, a private company limited by shares, registered in England and Wales on 14 July 2026 under company number 17337841. The registered office is Stoney Works, 8 Stoney Lane, London SE19 3BD, United Kingdom. That record is public and the link above opens it directly at Companies House, no login required.
Think about what's actually in a CSV. Payroll rows. A customer list with email addresses. Transactions from a bank export. Lab results. The ordinary way to convert one of those online is to upload it to a stranger's server, trust a retention policy you can't audit, and download the result.
This converter skips that. Parsing and PDF generation run in a Web Worker on your own device, which means there is no server in the loop that could keep your data — not a policy promise, an architectural one. Load the page, disconnect from the network, and the conversion still works. That's the test worth running.
It also happens to be faster. Nothing is waiting on an upload, a queue, or someone else's rate limit.
The main tool converts CSV files into paginated PDF tables — A4 or Letter, portrait or landscape, with the font size fitted to your columns. There's a reverse direction too: PDF to CSV pulls tables back out of a digital PDF, which is useful when someone sends you a report and you need the numbers rather than the layout.
The limits are worth knowing up front. A batch takes up to 10 files, 50 MB per file and 200 MB in total, and a table can run to 250,000 rows. Everything is held in your tab's memory, so those numbers are a practical ceiling rather than an arbitrary one.
Two honest gaps. It reads CSV, not XLSX — if your data is in an Excel workbook, export it to CSV first (File → Save As → CSV) and it'll convert fine. And PDF to CSV needs a digital PDF with selectable text; scanned pages need OCR, which isn't built yet. Complex tables with merged cells or multi-line rows may still want a cleanup pass after extraction.
It isn't. There's no paid plan, no ads, no affiliate links and no data being resold — a static site costs very little to run, and this tool does one job completely enough that there's nothing left to sell you. If that ever changes I'll write it on this page rather than quietly adding a limit, and what's free today stays free.
Same approach, different file types. There's pdfannotation.app for highlighting and signing PDFs without uploading them, wavtomp3.app for audio conversion in the browser, and websitefeedback.tools, a Chrome extension for leaving review comments directly on a live web page.
A CSV that converts wrong, a column that lands in the wrong place, a feature you keep wishing for — the contact form on the home page reaches me directly, or email stasmashkin.art@gmail.com. A sample file that reproduces the problem is worth ten paragraphs describing it.
