Parses an uploaded levels and bands CSV and returns a preview of the parsed rows along with a suggested column mapping. This validates and previews only; it does not persist anything or create a draft. The response is a JSON object with uploadData, an array of row arrays holding the raw cell strings for each data row, and columnMap, which pairs each CSV column header with the field it maps to (expectedColumnKey), or null when the header is not recognized. Recognized field keys are groupName, levelName, min, mid, max, compensationType, currency, and jobTitles. Use this to confirm a spreadsheet before writing; to persist the data, build the draft with Update Compensation Level Groups and Levels (update-compensation-level-groups-and-levels), Update Pay Bands (update-pay-bands), and Replace Job Title Level Assignments (replace-job-title-level-assignments), then publish it with Publish Draft Compensation Level Groups (publish-draft-compensation-level-groups).
