When CSV Exports Break in Excel (Fix with CSV to Excel)
Fix single-column CSV messes and encoding issues by converting to .xlsx with FileToolsHub’s free CSV to Excel tool.
Double-clicking a CSV often dumps every field into column A when Excel guesses the wrong delimiter or encoding. Marketplace and SaaS exports are frequent offenders.
Upload the CSV to /tool/csv-to-excel to produce a proper .xlsx with columns preserved. If you need JSON for an API instead, convert Excel with /tool/excel-to-json after, or go CSV→JSON on the spreadsheet hub.
Going the other way — sharing a sheet as CSV for a legacy importer — use /tool/excel-to-csv. Validate JSON fixtures with /tool/json-formatter when engineering consumes the data next.
FileToolsHub targets csv to excel online free fixes for ops teams who should not need Power Query for a one-off export.
