A ConvertCSV alternative

ConvertCSV has been doing browser-based conversion for far longer than we have, and it covers a long tail of formats that we do not. If you have used it and you are looking for something adjacent, here is an honest account of where the two differ.

Fair is fair: what ConvertCSV does well

Depth of coverage. It has accumulated a genuinely large catalog of conversions and options, including plenty of niche ones, and it does them in the browser rather than by uploading your file. That combination was unusual when it started and it is still not common.

The option surfaces are also deeper than most. If you need to control a specific quoting or escaping behavior on an unusual target format, there is a good chance they expose it and we do not.

Where the two differ

  ExploreMyData ConvertCSV
After the conversion Hand off to a full workbench with SQL, a pipeline and charts, carrying the same file A converted file to download; each page is a self-contained conversion
Binary and columnar formats Parquet, Arrow, Avro, SQLite, DuckDB, PDF and Excel read directly Strongest on text formats; check their catalog for binary coverage
What the tool tells you Notices for padded rows, renamed headers, detected delimiter and encoding changes Conversion output, with options you set yourself up front
Size handling A stated 100 MB cap per widget with a named handoff to a 1 GB editor Practical limits depend on the page and your browser

Competitor details are general and may change; verify current capabilities on their site. Statements about ExploreMyData are testable here, right now.

I used ConvertCSV for X. Where is that here?

There Here
CSV to JSONCSV to JSON, typed per column
CSV to XML or SQLCSV to SQL with four dialects, XML both ways
CSV to Markdown or HTMLCSV to Markdown, HTML table to CSV
Fixed-width parsingText to CSV, fixed width and delimited
Splitting a large fileCSV Splitter, header kept on every part

Both can be the right tool

If you have one unusual conversion and you want it done, use whichever site has a page for it. If your file needs looking at rather than converting, or if the conversion is the first of six steps, that is the case we are built for.

We do not make comparative privacy claims. Open your browser's network tab on either site and watch what happens when you drop a file; that is a better answer than anything either of us writes in marketing copy.

Questions people actually ask

Is ConvertCSV free?

It has been free to use for the conversions we have needed, at the time of writing. Check their site for current terms rather than relying on this page.

Does ConvertCSV upload my file?

Their converters have long run in the browser. We do not make competitive privacy claims about other people's tools: open your browser's network tab while you convert and you can see for yourself, on their site and on ours.

Why would I use ConvertCSV instead?

Breadth of niche conversions. They cover a very long tail of formats and options that we do not, built up over many years. If your conversion is unusual, they are more likely to have a page for it.

What do you do that they do not?

Nineteen input formats into one workbench with real DuckDB SQL, a forty-operation pipeline, and conversion notices that tell you what the tool did to your data. Their pages convert; ours convert and then hand you somewhere to keep working.

Can I move between the two?

Yes, and there is no lock-in on either side. Both produce plain files.

Convert something and see the notices

Every conversion reports what it did: rows padded, headers renamed, delimiter detected, orientation chosen.
