What does this Id value in the Modus v1 JSON output represent?

[jbielski]

Hi, I tried converting the a csv file from a Grower to modus json v1 using the web app's drag and drop functionality. I got back a result that had some ids in it that I don't understand.

For a row that looks like this in the csv file:

Date, Longitude, Latitude, Sample ID, Lab Number, OM [%]
3/31/21, -98.217732, 41.957938, 21567, 0.8

I got back this in the Modus v1 JSON:

"samples": {
"": {
"results": {
"-453dfa18bbb16cd0a1bb8249f3ce8aca": {
"analyte": "OM",
"units": "%",
"value": 0.8
},

What is "-453dfa18bbb16cd0a1bb8249f3ce8aca"? How was it derived? What could I add to the csv to make it look more like it does in equivalent XML:
<Depths> <Depth DepthID="1"> <NutrientResults> <NutrientResult> <Element>OM</Element> <Value>0.8</Value> <ValueDesc>VL</ValueDesc> <ModusTestID>S-SOM-LOI.15</ModusTestID> <ValueType>Measured</ValueType> <ValueUnit>%</ValueUnit> </NutrientResult>
