Keep leading zeros. Make SQL.
Only for Mac
Free · In‑App Purchases
Mac
Keep leading zeros and readable text when turning CSV into Excel. Conversion is free. Need SQL too? Start the optional 14-day Pro trial. No automatic charge.
Keep readable text and leading zeros when converting CSV to Excel on your Mac. Preview your data, check column types, and save an XLSX file. Excel conversion is free.
READABLE TEXT BEFORE YOU EXPORT
Convert CSV, TSV, TXT, JSON and JSONL to XLSX. Jotool detects text encodings and delimiters, including UTF-8, CP949 (EUC-KR) and Shift_JIS. Check the preview and choose the encoding yourself when needed.
KEEP IDENTIFIERS INTACT
Order IDs, phone numbers and postal codes are not always numbers to calculate with. Jotool preserves leading-zero values and identifiers beyond Excel's numeric precision as text. Review inferred column types or explicitly select Text for a column.
CONTINUE FROM EXCEL TO SQL
With Pro, turn CSV or XLSX into INSERT, UPDATE and IN-clause SQL for MySQL, PostgreSQL and SQLite. After Excel conversion, choose Open in SQL Generation. Review the generated statements, then copy or save them.
FREE AND PRO
• Free: Excel conversion and batch image conversion.
• Pro: SQL generation, local file search, screenshot organization with OCR search, and clipboard history.
• Start an optional 14-day Pro trial when you are ready.
• Continued Pro access requires a separate lifetime purchase at the displayed price. There is no automatic charge or subscription renewal.
• After the trial, existing clipboard history remains available for viewing, searching, copying, full backup and deletion.
PROCESSED ON YOUR MAC
No server upload is needed to convert files. Your files, search index, clipboard history and settings stay on your Mac. No account, ads, analytics SDK or user tracking. A stock symbol is sent to Naver Finance or Yahoo Finance only when you request a quote preview.
Requires macOS 13 or later.
