New

OR filters!

Previously, Rowboat was focused on filtering that would return rows matching all of the given conditions. We now support working with “OR” filters, which will return rows that match any of the given conditions. For example, Age: 0 to 18 OR 60 to 100 will return rows whose Age is within the 0 to 18 range as well as rows whose Age is within the 60 to 100 range.

To create a set of OR filters, hold Command (Mac) or Control (Windows) while hovering on a header entry (for example, bars or histogram).

Alternatively:

Create filters manually

In addition to clicking on header entries to filter, you can now create filters manually, which can be helpful for complex filter queries or datasets with many columns.

To create a filter, click the down arrow to expand the filter area and click “Add filter” (to create a single filter) or “Add OR filters” (to create a set of OR filters).

Other fixes

Add fallback message when JavaScript is not available
Condense space in top bar on narrow viewports
Improved functionality and accessibility for select component
Improve messaging on success and error messages on user pages
Improve handling of long filenames and search box on library page (Rowboat+)

2026-03-26T00:00:00Z

New: a filter tray to see many filters at once!
New: you can duplicate a column, which is useful if you want to play with edits but preserve the original column
New: the file name displayed at the top is now editable
Improved: for Rowboat+ users, the list of library files on the file selection page is now sorted most to least recently opened by default
Fixed: bug where uploading with a different file name does not reflect in the UI
Fixed: after signing in, you will be redirected to the original page you were trying to access

Highlights:

Cell editing! Hover on a cell, click on the “Edit cell” button, and enter the new value. As always, let us know if you run into any issues with this new feature.
When filtering, header charts will now keep colors consistent, so a color assigned to an entry will always use the same color for easy identification across subsets of data.

Other improvements and fixes:

Fix table cells not updating after changing column data type
Add “Cancel”/“Close” buttons to sharing dialogs
Choropleth maps: don’t zoom in when active areas are spread out across most of the map
