ERROR WARNING:
<field> is an invalid timestamp
HOW TO RESOLVE:
Use the template's second header row to view data type requirements and replace erroneous data in flagged fields accordingly. Accepted timestamp formats are listed in the second header row for the 'Audio Recording Time' field. Adjust cell formats for errored records or use find/replace to convert values to the correct type.
ADDED EXPLANATION:
Each field in the template requires a particular data type (text, integer, decimal, date-time, or true/false) or a controlled categorical response. Values that don't match these requirements will be rejected. In a spreadsheet, adjust cell formats or use find/replace to convert values—for example, changing numbers stored as text into actual numbers, converting decimals to integers, or trimming time-zone suffixes from date-time strings. For widespread issues in non-required fields, consider omitting the column entirely and re-uploading.
