Elasticsearch Bulk API using curl and text file - elasticsearch

Question

I'm a beginner with Elasticsearch and am following an "Essential Training" in LinkedIn Learning. I'm trying to follow with bulk loading API and the instructor is using Linux, I'm on Windows. He created a text file to read in with data using "VI". I just created a text file and pasted the data and removed the ".txt". The contents of the file, called reqs, is this:
{
"index":{
"_index":"my-test",
"_type":"my-type",
"_id":"1"
}
}{
"col1":"val1"
}{
"index":{
"_index":"my-test",
"_type":"my-type",
"_id":"2"
}
}{
"col1":"val2"
}{
"index":{
"_index":"my-test",
"_type":"my-type",
"_id":"3"
}
}{
"col1":"val3"
}
I've tried saving it with a carriage return (new line) after the last line and without. I saved this into my elasticsearch folder (C:\elasticsearch-7.12.0) which is the same directory I'm running the following command from:
c:\elasticsearch-7.12.0>curl -s -H "Content-Type: application/x-ndjson" -XPOST localhost:9200/_bulk --data-binary "#reqs"; echo
When I do this, I'm getting the following error:
{"error":{"root_cause":[{"type":"parse_exception","reason":"request body is required"}],"type":"parse_exception","reason":"request body is required"},"status":400}

Use this below curl command
curl -H 'Content-Type: application/x-ndjson' -XPOST 'localhost:9200/index-name/_bulk?pretty' --data-binary #reqs.json
reqs.json should look like this
{"index" : {"_index" : "my-test", "_type" : "my-type", "_id" : "1"}}
{"col1" : "val1"}
{"index" : {"_index" : "my-test", "_type" : "my-type", "_id" : "2"}}
{"col1" : "val2"}
{"index" : {"_index" : "my-test", "_type" : "my-type", "_id" : "3"}}
{"col1" : "val3"}
