Spreadsheet Converter

Convert XLS, XLSX, CSV, ODS free with AnyConv365 Spreadsheet Converter. Fast online file conversion — private by design, no account required.

Convert Excel, CSV, and ODS spreadsheets

AnyConv365 converts files between formats such as XLS, XLSX, CSV, TSV, ODS, PDF without requiring desktop software. Choose the output that fits sharing, editing, publishing, or archiving.

Simple conversions run locally when supported; more complex format pairs use a conversion server. Server-processed files are deleted after the job.

How to use: add a XLS, XLSX, XLSM, XLSB, CSV, ODS, TSV, PDF, JSON, XML, YAML, Apple Numbers file, then choose XLSX, CSV, PDF, HTML, JPG pages (ZIP), PNG pages (ZIP), XLS, ODS, TSV, JSON, XML, YAML as the output format and start the conversion. For CSV, TSV, XLSX, JSON, XML, or YAML output, use files no larger than 32 MB; split larger spreadsheets first. Excel 2003 XML files are supported; if a workbook has several sheets, the first sheet is converted. Text files automatically recognize UTF-8, UTF-16, GBK/GB18030, Big5, Shift_JIS, EUC-KR, and common Western encodings, so you normally do not need to change the encoding first. PDF table export works with selectable text and does not OCR scanned pages. JSON must be a top-level array of objects; nested fields are flattened into columns. Macro-enabled Office files are opened without running macros. Converted files do not preserve VBA macros.
