Browse spreadsheets and tables in your browser
Open a local file or drop it into the viewer. Switch worksheets, scroll through cells, adjust zoom, and inspect cell contents. Excel workbooks retain their existing reading experience. CSV and TSV files appear as a single worksheet; use Separator and Text encoding to correct detection. Text columns keep leading zeros, long identifiers, and date-like strings unchanged.
Supported formats include Excel XLSX, XLSM, XLTX, XLTM, XLS and XLSB; CSV and TSV; ODS and FODS; Numbers 3.0 and newer; compatible WPS ET/ETT and UOS spreadsheets; DIF, SLK, PRN and DBF; Lotus WK1/WK3/WK4/WKS/123; Quattro Pro WQ1/WQ2/WB1/WB2/WB3/QPW; Works XLR; and EtherCalc ETH. Compatibility depends on the version and features used in each file. Legacy formats focus on cell data rather than reproducing every visual detail.
Privacy and compatibility
Files are processed locally and are not uploaded or saved by this tool. Fonts come from your device; no online fonts are requested. Formula cells show saved results when available. Formulas are not recalculated, macros never run, external data connections are not refreshed, and document links do not load automatically.
Numbers tables appear as separate worksheet tabs, with original sheet/table names where available. Older Numbers documents from before Numbers 3 are unsupported. DBF companion memo files are not loaded. PRN uses the fixed-width Lotus/Excel layout; arbitrary print files are unsupported. Charts, drawings, pivot features, fonts, and some styling may be missing in imported formats. A compatibility note appears alongside the document when these limitations apply.
There is no fixed file-size or sheet-count cap. Actual browser memory and archive-expansion safeguards still apply to complex files. Encrypted or damaged workbooks cannot be opened. This viewer does not edit, export, or print spreadsheets.
