Work out whether an unfamiliar text export uses commas, tabs, semicolons, or pipes. The detector samples quoted records so separators inside quoted text do not inflate the score.
This tool performs a focused delimiter analysis in local browser memory. It creates a separate downloadable result rather than presenting the original upload as processed.
Complex Excel features such as VBA, external links, charts, and advanced formatting may not survive browser-based workbook rewriting. Use a copy of important files.
Files are parsed locally. Support is intentionally limited to the formats shown below and advanced workbook features may not be preserved.
