Convert UTM Coordinates in Sheets
Formula
The API handles all 60 UTM zones and both northern and southern hemispheres with high precision calculations based on the WGS84 ellipsoid model.
=VERVE("utmconverter", A2, B2)=VERVE.CALL("utmconverter", A2, B2)A2 holds latitude, B2 holds longitude. Arguments go in that order — the same order as the table below.
With literal values
Nothing has to come from a cell — typed values work the same way.
=VERVE("utmconverter", 40.7128, -74.006)Inputs
Required inputs are positional, in the order below. Everything else is passed as a "name", value pair after them — the same shape as SUMIFS.
| Input | Type | Where it goes | Description |
|---|---|---|---|
latitudeRequired | number | argument 2 | Latitude (-90 to 90) (e.g. 40.7128) |
longitudeRequired | number | argument 3 | Longitude (-180 to 180) (e.g. -74.006) |
direction | string | "direction", value | Conversion direction (e.g. to_utm) |
Passing an option
=VERVE("utmconverter", A2, B2, "direction", "to_utm")What lands in your sheet
With no "field" pair the formula spills the whole response as two columns — field name on the left, value on the right — starting at the cell you typed in. Make sure the cells below and to the right are empty.
Pulling one value
Add a "field" pair to get a single cell back instead of a table. The field name is the dot-path from the table below.
=VERVE("utmconverter", A2, B2, "field", "conversion")=VERVE.CALL("utmconverter", A2, B2, "field", "conversion")Available fields
| Use as "field" | Type | Example cell value | Description |
|---|---|---|---|
conversion | string | lat/lon to UTM | Type of conversion performed (UTM to lat/lon) |
input | object | {…} | |
input.latitude | number | 40.7128 | Input latitude coordinate value |
input.longitude | number | -74.006 | Input longitude coordinate value |
output | object | {…} | |
output.zone | number | 18 | UTM zone number (1-60) for converted coordinates |
output.hemisphere | string | N | Hemisphere designation (N for north, S for south) |
output.easting | number | 583959.37 | UTM easting coordinate in meters |
output.northing | number | 4507351 | UTM northing coordinate in meters |
formatted | string | 18N 583959E 4507351N | Human-readable formatted lat/lon string |
datum | string | WGS84 | Geodetic datum used (WGS84) |
Filling a whole column
Hand the first argument a range instead of a cell and the add-in makes one batched call for the lot, then spills the answers down. That is faster than dragging the formula and costs the same credits — one per row looked up.
=VERVE("utmconverter", A2:A100, B2, "field", "conversion")=VERVE.CALL("utmconverter", A2:A100, B2, "field", "conversion")A2:A100 is the column of latitude values. The result spills down alongside it, one row per input, blanks skipped.
When a cell doesn't fill
A failed lookup returns readable text starting with #ERR rather than a spreadsheet error, because Excel cannot show a custom message on a real error — you would get a bare #VALUE! with no reason. The trade-off is that IFERROR() won't catch it; test with LEFT(cell, 4) = "#ERR" instead.
| Cell reads | What happened |
|---|---|
#ERR Not connected | No API key saved. Open the side panel and connect your account. |
#ERR Replace <name> with a cell or value | The preview formula was copied as-is. Swap the placeholder for a cell reference. |
#ERR No "x" in utmconverter | An option name that this source doesn't take. The message lists the ones it does. |
#ERR No data point "…" | The "field" path isn't in the response. Check the dot-path against the table above. |
#PREMIUM(field) | The field exists but your plan doesn't include it. |
#ERR Out of credits | The month's credits are spent. Usage resets on your billing date. |
Before the formula works
The add-in reads the API key you saved once in the side panel — the key never goes in the formula, so a shared sheet doesn't leak it and a collaborator without access simply sees the last calculated values.
- Install the add-in for Google Sheets or Excel.
- Open the side panel and sign in, or paste a key from your dashboard.
- Type the formula above into any cell.

Frequently asked questions
Does Convert UTM Coordinates in Sheets work in both Google Sheets and Excel?
Yes — the same source, the same arguments. Sheets calls it =VERVE("utmconverter", …) and Excel calls it =VERVE.CALL("utmconverter", …); that function name is the only difference.
Do the cells recalculate on their own?
They recalculate when the sheet does — on edit, on open, or on a manual recalc. Each recalculation is a fresh call and spends credits, so for a large static column it's worth copying the results and pasting them as values.
How many credits does a filled column cost?
1 credit per row looked up, whether you drag the formula or pass a range. The range form is one HTTP call instead of many, but the credit count is the same.
Can I share the sheet without sharing my key?
Yes. The key is stored against your account, not in the file. Collaborators see the values already in the cells; formulas only recalculate for someone who has connected their own account.
Why is a cell showing #ERR instead of an error?
So you can read the reason. Excel can't display a custom message on a real spreadsheet error, so the add-in returns the explanation as text on both platforms instead.
