POLYEXPORT - POLYMARKET EXPORTER

STOP COPYING POLYMARKET DATA BY HAND

You open a Polymarket event because you want to compare outcomes, check probabilities, or save a snapshot. Then the page turns into work. One row says 42%. Another says 11%. Volumes are scattered across the layout. By the time you paste everything into a spreadsheet, the market may have already moved.

That is the real friction. The information is visible, but it is not ready to use.

PolyExport fixes that.

WHY THIS IS HARD

Polymarket events are easy to browse and much harder to work with once you want a structured dataset.

- Multi-outcome events spread useful numbers across many cards
- Price ladders are readable on screen but awkward to compare in a table
- Manual copy and paste is slow and error-prone
- Snapshotting a market at a specific moment takes more effort than it should
- Reference context is often mixed into the page instead of being laid out as a clean dataset

Most people solve this with a messy spreadsheet, a few screenshots, or a script they do not want to maintain. That is fine once. It is painful if you do it often.

This extension is built for that exact gap.

WHAT THIS EXTENSION DOES

PolyExport runs on the Polymarket event page you are already viewing and turns that event into a structured export file.

It does not ask you to build a spreadsheet first. It does not make you copy rows one by one.

Here is what you get:

Current event detection — Open a Polymarket event and the extension detects the event automatically.

One-click export — Export the current event as CSV, XLSX, JSON, HTML, or TXT.

Structured market rows — Each outcome is converted into a clean row instead of page fragments.

Useful analysis columns — Exports can include the original market title, asset, direction, strike price, month, yes price, no price, implied probability, 24h volume, total volume, snapshot time, and source URL.

Reference-price context — For supported pages, the extension reads visible page context and adds reference price, distance to strike, and distance percent.

Timestamped snapshots — Every export reflects the market state at the moment you click export.

Local file creation — The export file is created on your device, so you can move it into Excel, Numbers, Google Sheets, Notion, Airtable, or your own scripts.

HOW IT WORKS

1. Open a Polymarket event page.
2. Click the PolyExport extension.
3. Choose your export format.
4. Export the current event.

That is it. The page you are already looking at becomes a structured file you can sort, filter, save, or analyze.

WHY THE EXTENSION USES A POPUP

Most export tools become cluttered when they try to add controls directly into a live market page.

This extension keeps the workflow simple. The market stays untouched. The popup handles format selection and export in one small step.

That makes the extension easier to use when you only need a quick snapshot and do not want extra UI injected across the page.

EXPORT FORMATS

CSV

Best for spreadsheets, filters, quick sorting, and lightweight analysis.

XLSX

Useful when you want a ready-to-open Excel file without importing CSV manually.

JSON

Useful for scripts, data pipelines, custom dashboards, and developer workflows.

HTML

Useful when you want a readable export that opens cleanly in a browser.

TXT

Useful for simple archiving or plain-text sharing.

REAL SCENARIOS WHERE THIS HELPS

Comparing a strike ladder:
You open an event with 15 or 20 outcomes and want to compare how the market prices each strike. Instead of jumping across the page, you export once and sort by strike price, probability, or distance.

Saving a snapshot before news moves the market:
A market is reacting to a headline and you want a record of the exact state before it changes again. Export once and keep a timestamped file for later comparison.

Reviewing which outcomes actually have activity:
Some outcomes look interesting until you see the volume next to them. Exporting makes it easy to compare probabilities with 24h and total volume in the same view.

Moving data into a spreadsheet model:
If you already work in Excel, Numbers, or Sheets, this extension gives you a cleaner starting point than manual page copy and paste.

Checking distance from the current reference price:
For price-ladder markets, the export can show how far each strike sits from the visible reference context on the page. That gives you a faster way to scan what is near, far, crowded, or priced aggressively.

Keeping a local archive:
If you revisit the same market over time, you can save repeated exports and build your own history without setting up a separate database first.

WHAT THIS EXTENSION DOES NOT DO

It does not place trades.
It does not access your Polymarket account.
It does not upload your exports to a remote server.

The only permissions it uses:
- activeTab — to access the Polymarket tab you explicitly opened and clicked from
- scripting — to read visible page text needed for export context such as reference-price information
- access to https://gamma-api.polymarket.com/ — to fetch the current event and market data used in the export

That is all. The extension is focused on export, not account access or background tracking.

PRIVACY

PolyExport only works on the active Polymarket event page when you use it.

It reads the visible page and fetches event data needed to build the export file. The exported file is created locally on your device.

There is no account creation flow inside the extension.
There is no sign-in requirement inside the extension.

WHO THIS IS FOR

- Polymarket users who want structured exports instead of manual copy and paste
- Spreadsheet users who want cleaner event data for sorting and filtering
- Researchers and analysts who want timestamped market snapshots
- Developers who want quick JSON or tabular exports without writing a one-off scraper first
- Anyone tracking multi-outcome events where a simple page view is not enough

GETTING STARTED

Install the extension, open a Polymarket event, and export the current event in the format that fits your workflow.

No account setup inside the extension. No spreadsheet prep. Just open a market and export the data you need.
