Plotiq's CSV cleaner is free forever. Trim, dedupe, and strip formatting noise from as many files as you want — no trial, no usage cap below 5,000 rows.

Keep it as a bookmark — it's the fastest CSV tidy-up on the web.

1. Load any CSV — free, no sign-up

Drop a file or paste CSV text. Zero email gate, zero trial countdown.

2. Run the cleaners that apply

Each cleaner is opt-in. Watch the output pane update in real time as you toggle each one.

3. Download the tidy result

Unlimited downloads, no watermark. Use the clean CSV in any chart tool, spreadsheet, or pipeline.

Why is the CSV cleaner free?

Plotiq is a client-side app — no storage or compute on our side — so there's nothing to charge you for.

Are there ads in the free CSV cleaner?

No ads. No tracking pixels. No retargeting.

Can I use the free CSV cleaner on confidential data?

Yes — the tool is browser-only, so your file never touches our servers. It's safe to use on HR, finance, or medical CSVs where upload would be a problem.

Is the free cleaner output watermarked?

No. The output is a plain CSV — no branding, no footer, no metadata tag.
