MetaMask CSV to Excel / Google Sheets

Excel / Google Sheets won't take your MetaMask CSV directly — TurboTax removed crypto CSV import in January 2026 and the legacy importer capped at ~4,000 rows. Upload your export here and download a CSV that imports without the cap.

Why MetaMask users get stuck at Excel / Google Sheets

The MetaMask details that trip up a clean Excel / Google Sheets filing — and how the converter handles each.

Note 01

MetaMask itself doesn't issue a tax CSV — export the wallet's transaction history from Etherscan, or use an aggregator that reads the address, and upload that.

Note 02

On-chain swaps, bridges, and gas fees each carry tax consequences a raw Etherscan export won't classify — an aggregator's Form 8949 CSV is cleaner.

Note 03

Self-custody means there is no broker basis at all, so most wallet lots need cost basis supplied before they can be filed.

MetaMask to Excel / Google Sheets FAQ

Which MetaMask export should I upload?

Upload the wallet transaction CSV (Etherscan or aggregator) from Etherscan → Export, or an aggregator that reads your address. MetaMask itself doesn't issue a tax CSV — export the wallet's transaction history from Etherscan, or use an aggregator that reads the address, and upload that.

What exactly do I download?

A Form 8949 CSV — one row per disposal with description, acquisition and sale dates, proceeds, cost basis, gain/loss, and any wash sale adjustment. Open it in Excel or Google Sheets, or hand it to your CPA.

Does the 4,000-row limit apply here?

No. The ~4,000-row ceiling was specific to TurboTax's old crypto CSV importer. A plain CSV worksheet has no row cap, so even a heavy MetaMask trading year comes through in full.

Are wash sales handled?

If your CSV includes wash sale figures, they pass through using the standard crypto codes (322 short-term, 324 long-term). The IRS has not formally extended the wash sale rule to digital assets for the 2025 filing year, so we honor whatever your source reports rather than inferring new adjustments.

Is my file stored anywhere?

No. Your upload is processed in memory and deleted when the conversion finishes. The output bundle stays available for 24 hours, then is removed. There's no account to create.
