Julian Day Conversion in Google Sheets & Excel — =VERVE("julianday", A2)

What this pulls

Convert dates by the row. =VERVE("julianday", A2) turns a Gregorian date into its Julian Day Number down a column — Google Sheets or Excel.

It's one of 300+ live sources you reach with a single =VERVE()function — served from APIVerve's production data engine, billed at 1 credit per resolved cell, and refreshed on whatever cadence you set. No API keys to wrangle, no scripts, no exports.

Ways to use it

One value per row

Fill =VERVE("julianday", A2) down a column and Julian Day Conversion returns a result for every row — a batch of live values in a single drag, no code.

Enrich data in place

Add Julian Day Conversion beside a table you already have to append its output right where your data lives, then sort, filter, or chart on it.

Stays fresh on its own

Set the sheet to refresh on a schedule and the julian day conversion values keep themselves current without anyone re-typing.

Use it in your sheet

The same function works in both apps — install once, sign in with your key, and type it into any cell.

Google SheetsAdd-on

Install from the Workspace Marketplace, then drop the formula into a cell. Autocomplete suggests the source and its fields.

=VERVE("julianday", A2)

Microsoft ExcelAdd-in

Same function, same arguments, same key — in Excel on desktop, the web, or mobile. Drag to fill a whole column.

=VERVE("julianday", A2)

Fields you can pull

Add a field name as the last argument to land just that value in the cell.

Everything you need to wire it into a sheet.

How do I pull Julian Day Conversion into a spreadsheet?

Install the VerveSheets add-on, sign in with your key, and type =VERVE("julianday", A2) into any cell. The same function works in Google Sheets and Excel — no scripts, no API wiring.

How many credits does each Julian Day Conversion cell cost?

Each resolved cell costs 1 credit. Filling a column of ten rows costs ten times that; a cell only re-bills when it actually refreshes, so a static sheet doesn't keep charging.

Can I fill a whole column at once?

Yes. Reference a range instead of a single cell — e.g. point Julian Day Conversion at A2:A50 — and it returns a value for every row in one call, or just drag =VERVE("julianday", A2) down like any spreadsheet function.

Does Julian Day Conversion work in Excel as well as Google Sheets?

Yes. It's the same =VERVE() function with the same arguments and the same key in both — build a sheet in one and it behaves identically in the other.

How current is the data?

Julian Day Conversion is served live from APIVerve's production data engine, and cells recalculate on the refresh cadence you choose — every open, hourly, or every 30 minutes.

Where does the data come from, and what shows on my bill?

VerveSheets runs on APIVerve, our production data engine; Julian Day Conversion is one of 300+ sources on the same key. Invoices and card statements show APIVERVE.
