Convert Word, Excel, and PowerPoint files, reshape CSV data, and preview documents without desktop suites—organized by application family.
Office interoperability primer
Knowledge workers constantly shuttle between DOCX briefings, XLSX forecasts, PPTX decks, and CSV extracts from CRMs. When IT locks installs or you are on a Chromebook in an airport lounge, browser converters bridge the gap—provided you understand what survives the trip (values vs formulas vs macros).
Word workflows emphasize canonical exports: PDF for immutable sharing, HTML for lightweight portals, Markdown for docs-as-code teams. Excel workflows split between structural conversions (CSV/JSON for pipelines) and presentation exports (PDF for leadership snapshots). PowerPoint utilities focus on combining presenter edits or shrinking bloated media.
CSV remains the duct tape of data integration. Cleaning duplicates, escaping mangled quotes, and generating SQL stubs are weekly chores for analysts—grouped here so you do not need to remember twenty bookmark names.

About Word, Excel, PowerPoint & CSV browser tools
Word, Excel, PowerPoint & CSV
- Why did accented characters rot when CSV opened in Excel?
- Excel infers ANSI unless UTF-8 BOM or import wizard steps appear. Export UTF-8 explicitly from the converter pages here and teach teammates to use Data → From Text instead of double-clicking raw CSV.
- Merged PowerPoint blew past email limits—what shrinks it fastest?
- Compress embedded photos inside the deck or swap linked media references before PDF export. The compress utility linked above targets oversized imagery inside PPTX containers.
- Word-to-PDF broke my custom font—who’s wrong?
- Embedding rights vary by font license. Browser converters substitute metric-compatible fonts when embedding is blocked—embed outlines on desktop first if brand police demand pixel-perfect spacing.
- Excel JSON export dropped NaN cells—intentional?
- JSON lacks a native NaN literal; exporters typically coerce to null or strings. Document that mapping before piping into strict TypeScript parsers.
