Advanced Tools
Tools that would normally require an upload, an account or a desktop install — running entirely in your browser instead. These use WebAssembly to do genuinely heavy work locally, so the only limit is your own machine rather than someone else's upload cap. They download more on first use than the instant tools, and cache afterwards.
CSV & SQL Data Playground
Open CSV files too big for Excel and query them with SQL — no upload.
Image to Text (OCR)
Pull the text out of a screenshot, scan or photo — read on your device.
Batch Workspace
Drop up to fifty files, pick one operation and download one ZIP: resize, convert, compress, strip metadata, hash, normalise, rename or inspect.
Which advanced tool?
One line each: the situation the tool is the answer to.
| Tool | Best when |
|---|---|
| CSV & SQL Data Playground | A CSV or Parquet file too big for a spreadsheet, queried with SQL. |
| Image to Text (OCR) | Text trapped in an image or a scanned page. |
| Batch Workspace | Many files that all need the same thing done: resize, convert, hash, rename, normalise. |
About these advanced tools
WebAssembly is what moved this category into the browser: it lets engines written in systems languages run at close to native speed inside a tab. The SQL playground runs a genuine column-oriented database that reads your file in byte ranges from disk, which is why a CSV in the hundreds of megabytes — far past any spreadsheet's row limit — is workable without the file going anywhere or being loaded whole into memory.
The trade these tools make is deliberate and disclosed: the engine is a one-time download measured in tens of megabytes, cached after first use, in exchange for removing the upload, the waiting queue and the question of what happened to your data afterwards. For a dataset you are not allowed to hand to a third party, that trade is not a convenience — it is the difference between being able to do the analysis and not.
