To use CSV or TXT files in your organization, the file must include location fields. The following sections contain information about supported data formats in CSV and TXT files, and what you need to consider when adding CSV and TXT files to a map. Other separators are not supported.Īs no data types are enforced in the file, ArcGIS Online relies on the field names and specific formatting in the fields to interpret the data type that should be applied. In TXT files, fields can be separated with a comma, semicolon, or tab. In CSV files, fields are always separated by commas. The first row in the file defines the names for all subsequent fields. If the CSV file contains address or place information, updates made to the CSV file on the web will not be reflected in the map.ĬSV and TXT files store information in plain text. If the CSV file contains coordinate information, updates made to the CSV file on the web will appear in the map. If the CSV file is stored on a publicly accessible website, you can reference it from the map in Map Viewer or in Map Viewer Classic as a layer on the web.

When you add a CSV file without location information to Map Viewer, a table layer is published and added to the map. This is useful when you want to join nonspatial data-for example, property damage claims related to a recent tornado-to spatial data such as a ZIP Codes layer using the Join Features analysis tool.
