About DataWork Tools

DataWork Tools provides free browser-based tools for spreadsheet and data preparation. The English edition includes 22 data tools and a batch image resizer with practical examples and operation-specific limits.

Results are intended to be reviewed before use. XLSX support is a limited OOXML value reader, not full Excel compatibility. No account, file upload service or advertising integration is used. Anonymous page views and tool submission attempts are counted without visitor identifiers.
