Open RDATA files in your browser
The file R saves a whole workspace in, every object at once. Open one right here and see what it holds, with no R or RStudio. Nothing leaves your device.
Or drop it anywhere on this page
What you'll see
Your R data opens as its objects, each with its kind and first values, without R.
- Every object • Its class, size and first values
- Each data frame or matrix opens as a table
- Lists and attributes unfolded in the Tree
- Export • Save a table as CSV, Excel or Parquet
About RDATA
R saves objects with save, or the whole session with save.image, into .RData, and packages keep their datasets as .rda. RStudio offers to save the workspace as .RData when it closes, so many projects have one.
An RData starts with RDX2 or RDX3, then a list of named objects in R's serialization: each with its type, its attributes, such as class, names, factor levels and row names, and its values, packed with gzip unless it was saved with bzip2, xz or nothing.
Filepeek reads the file itself and never runs R or anything in it. The Workspace lists every object with its kind and first values, each data frame or matrix opens as a table, factors by their levels and dates as dates, to save as CSV, and lists unfold in the Tree. Functions show only as functions.

Questions
How do I see what's in an .RData without R?
Drop it on this page. Every object shows with its kind and first values, and each data frame opens as a table.
Can I export a data frame from an .RData to CSV?
Yes. Open it from Tables, then choose Export and Save as CSV, Excel, JSON or Parquet.
What is the difference between .RData and .rds?
An .RData holds any number of named objects, which load back under their names. An .rds holds one object without a name. Both open here.
Is it safe to open an .RData someone sent me?
Here it is: Filepeek only reads its values and runs none of the code a file can hold. In R itself, a file made to do harm can run code as it loads, so open there only files you trust.
