Importing a large CSV file directly into ArcGIS Pro using the Table To Table conversion tool results in data inaccuracies in the output with no warning triggered in the tool.

Solución alternativa

Create a schema.ini file in the directory containing the CSV using the following entries:

[nameOfCSV.csv]

Col2=GRID_ID Double
