How to Connect Beaconchain to Excel (4 Methods Compared)

The Problem With Getting Workbook Data In and Out of Beaconchain

You have an Excel workbook full of validator indices, Ethereum addresses, and epoch ranges. You need balance histories pulled in, income breakdowns written out, or reward summaries built for investors — in a way that doesn't mean a manual API session every single time.

Beaconcha.in is the de facto analytics layer for the Ethereum Beacon Chain. But getting its data into a workbook is an exercise in patience by default. The usual flow is exporting CSV from the web UI, importing into Excel, realigning columns, and hoping the epoch format matches what your formulas expect.

Below are the four common ways teams handle this. Only the last one scales.

Method 1: Manual CSV Export

The default for Excel users. Export from beaconcha.in, open in Excel, reformat the date columns, realign the validator headers, paste into the right sheet. For five validators it's a half-hour job. For fifty it's a recurring afternoon.

What makes this grind particularly corrosive is that validator data is precision-sensitive. A misaligned epoch column or a gwei value that lost a decimal during import produces yield calculations that look correct until someone compares them against the on-chain total. Staking rewards don't pause while you recheck the import format.

Method 2: Power Automate

Power Automate has HTTP action support that can call the Beaconcha.in API on a schedule and write the response into an Excel workbook via the Excel connector.

Before continuing: are you comfortable with REST APIs? With parsing JSON and mapping nested properties into flat Excel columns? With building a loop that iterates over 50 validator indices and handles partial failures gracefully? If those words feel like a different language, this method is not the fastest path for you — move to Method 3 or 4.

For those still reading: the automation works. The challenge is that Beaconchain's API returns data in shapes that vary by endpoint — balance history looks different from income history, which looks different from withdrawal records. Each requires its own mapping logic. And Power Automate's Excel connector writes one row at a time, which means a 90-epoch pull across 50 validators is 4,500 individual write operations.

Running that kind of automation at any real scale is slow and expensive.

You probably just need the reward summary for your 80 validators. You probably have no idea how to build a Power Automate flow that flattens nested arrays into a flat Excel table. So the work either sits undone, or it lands on whoever in your org has built these flows before — and they have a queue.

Every chained step adds cost, a new failure mode, and another person who has to understand the setup when something breaks.

Method 3: The Previous Generation — Connector Add-Ons

Until recently, the most practical option for repeatable Beaconchain-to-Excel workflows was a category of add-ons that let you define column mappings and run them on demand. You picked the endpoint, you tagged the fields, you saved a config, you ran it.

That was a meaningful improvement over CSV exports. The output was consistent, the config was reusable, and you didn't have to reconstruct the column layout every session.

But the field mapping was still yours to maintain. The epoch ranges were still yours to specify. The logic for which validators to include, whether to convert gwei to ETH, whether to skip slashed validators — all of that lived in your head, not in the tool. The data got through, but the thinking stayed on you. And whenever Beaconcha.in updated a field name or changed a response shape, your config quietly broke until someone went back in and fixed it.

This is the previous generation. It worked, but only as well as the person operating it.

The Easy Way: Using SheetXAI in Excel

There is a different approach entirely. SheetXAI is an AI agent that lives inside your Excel workbook. It reads your validator indices, understands the structure of what you're working with, and through its built-in Beaconchain integration it can pull balance history, income breakdowns, withdrawal records, or network state for you. No field mapping, no endpoint configuration, no reformatting. You just ask.

Example 1: Pull balance history for a portfolio

Fetch Beaconchain balance history for all validator indices in column A of my Excel table and write epoch number, effective balance, and total balance for each validator into separate column groups — start at column C

SheetXAI pulls the last N epochs for every index in the column, writes each validator's data into its own column group, and labels the headers automatically.

Example 2: Build an income breakdown for tax filing

Pull Beaconcha.in income history for all validator indices in column A of my Excel table and write epoch, attestation rewards in gwei, proposer rewards in gwei, and MEV tips — one row per epoch per validator, starting in row 2 of the Income worksheet

The pattern: instead of pulling raw balance data and then computing income deltas yourself, you ask for the income endpoint directly and get the breakdown already parsed. SheetXAI handles the per-validator iteration and the column layout in one step.

Try It

Get the 7-day free trial of SheetXAI and open any Excel workbook with validator indices in a column, then ask it to pull balance history or income data for your portfolio. The Beaconchain integration is included in every SheetXAI plan.
