If you regularly work with on-chain data, you already know how tedious it is to manually gather information from block explorers. The Blockchain Explorer Data Export Tool is a Chrome extension designed to eliminate that friction — letting you pull wallet profiles, transaction histories, token balances, and custom labels from Etherscan, Snowscan, Basescan, and Kromascan in seconds. Whether you are a crypto trader, tax professional, DeFi user, or blockchain developer, this tool gives you clean, structured data without the copy-paste grind.
What Is the Blockchain Explorer Data Export Tool?
The Blockchain Explorer Data Export Tool is a browser extension that automates the process of collecting and downloading data directly from popular EVM-compatible block explorers. Instead of manually navigating through pages and copying individual fields, you simply open the extension, select your preferred export format, and download everything you need in one action. It supports JSON, CSV, and plain text formats, making it compatible with spreadsheets, tax software, databases, and custom dashboards alike.
Key Features
Multi-Chain Support
The extension works across four major blockchain networks out of the box: Ethereum via Etherscan, Avalanche via Snowscan, Base via Basescan, and Kroma via Kromascan. All are EVM-compatible, so the extension integrates consistently across each explorer without requiring separate configurations. Additional chains will be added as the ecosystem grows.
Multiple Export Formats
You can export your data as JSON for developer workflows and database imports, CSV for use in Excel, Google Sheets, or crypto tax platforms, or plain text for quick human-readable review. This flexibility means you rarely need to reformat data after downloading — it comes out ready to use in whichever tool you prefer.
One-Click Export
The entire export process is triggered with a single click from the extension popup. There are no scripts to write, no API keys to configure, and no waiting for rate-limited requests. The extension reads the explorer page directly and packages the data immediately.
Batch Address Processing
For users managing multiple wallets, the extension supports exporting data from several addresses in sequence without having to repeat the process manually for each one. This is particularly useful for portfolio managers, compliance teams, and developers who need consolidated records across wallets.
Comprehensive Data Coverage
Each export can include wallet address details, full transaction history, ERC-20 and native token balances, and any custom labels or notes associated with an address. You get a complete picture of on-chain activity rather than a partial snapshot, which is essential for accurate reporting and analysis.
Privacy-First Architecture
The extension does not send your data to any external server. All processing happens locally within your browser, meaning your wallet addresses and transaction records stay entirely under your control. No account registration is required to use the tool.

Why Crypto Professionals Love It
Tax professionals use this tool to generate client reports without manually transcribing transaction data. DeFi users rely on it to track yield farming returns, staking rewards, and liquidity positions across chains. Blockchain developers pull structured data directly into their applications without building custom scrapers. Compliance officers maintain audit-ready records without dedicating hours to data collection each reporting cycle. For anyone who works with on-chain data regularly, the time saved is significant — and so is the reduction in human error that comes from eliminating manual entry.
