No re-upload neededThese tools accept .XLSX - your file is handed over directly.
No. Everything runs in your browser - your file never leaves your device. How this is verifiable
LibreOffice Calc and OpenOffice Calc save by default in the open .ods format - technically mature, but a client, accountant or colleague running a pure Microsoft Excel setup often cannot open an .ods file without extra software. This tool builds a genuine .xlsx workbook from your .ods spreadsheet, so the recipient can just double-click it in Excel like any other file.
The tool reads the whole spreadsheet directly in your browser: numbers, text, the last calculated formula results, number formats and ranges merged across several cells all move into the new workbook completely. The process needs neither an account nor an internet connection after the page has loaded once.
And the visual design? A small dedicated module writes the produced XLSX file's styles.xml directly: bold/italic/underlined text, font colour, cell background, border lines and alignment from the ODS file actually arrive in the new workbook. The number-format template itself (number, percentage, currency, date, time) is also translated from the ODS data-style definition into the matching Excel format code, so e.g. 10% no longer arrives as a bare 0.1. Only conditional formatting, embedded charts and rarer format variants (such as scientific notation or a condition-coloured negative number) stay out of technical reach.

Limitations: Numbers, text, formula results and merged ranges move fully into the new workbook. The most common number formats (number, percentage, currency, date, time) are translated from the ODS file into the matching Excel format code; rarer format variants (e.g. scientific notation or a condition-coloured negative number) are not represented. Bold/italic/underlined text, font colour, cell background, borders and alignment from the ODS file are carried over into the XLSX too. Conditional formatting and embedded charts from the ODS file cannot be represented when writing XLSX. Encrypted, password-protected .ods files are rejected.
No. The conversion runs entirely locally in your browser - nothing is sent anywhere.
Yes, mostly: font style, font colour, cell background, borders and alignment are carried over. Conditional formatting and charts are not.
Yes, it is a standards-compliant .xlsx file and opens in Excel, LibreOffice and Google Sheets.
No, an encrypted file is rejected with a clear message. Remove the password in the source application first.
