I use online geojson editors very regularly to create and edit geographical data. I find online editors particularly useful for tidying up and minimizing third-party data which I have downloaded from elsewhere. For example an editor can be very useful for previewing data exported from overpass turbo, and then manipulating that data into a format that you can then use with any of the popular javascript mapping libraries.
Vector GeoJSON is another popular and useful online GeoJSON editor. Like geojson.io this online editor can be used to create or edit GeoJSON data directly from your browser. Using Vector GeoJSON you can import data which you have saved from elsewhere. Alternatively you can create data from scratch by adding points or polygons to the Vector GeoJSON map. When you have finished creating or editing your spatial data you can save it as a GeoJSON file. Vector GeoJSON also has an option to covert your GeoJSON to a shapefile (via the ogr2ogr web client).
Geoman's Geojson Editor is another option for editing geojson data online. Using the Geojson Editor you can create, view, edit and share geospatial data in your browser. Where the Geojson Editor excels is in its excellent drawing tools.
The GeoJSON editor uses Geoman's own Leaflet-Geoman drawing tools to help you create your spatial data. These drawing tools allow you to add squares, circles and lines to an interactive map and then grab the geojson data to export the data to your mapping projects. I particular like the 'cut layers' tool which allows you to create holes in your polygons (sometimes known as canvas masking).
When you have finished manipulating your geographical data with Geojson Editor you can download the data you've created as a geojson file or in KML, CSV, TopoJSON, WKT and shapefile formats.
Placemark Play
Placemark Play is an open source online geodata editor which can be used to import and manipulate geographical data and then export the data in a number of different formats. The editor features a number of drawing tools which allow you to draw points, lines and polygons directly onto a map.
Unlike many of the other online geodata editors Placemark Play includes a number of editing tools, which allow algorithmic operations on your data, like buffering. When you have finished manipulating geodata with Placemark Play you can export your data in geojson, KML, CSV, topojson and shapefile formats. You can also export a snapshot of your completed data as an SVG image.
geojson.io
I definitely use geojson.io more than any other geographical data editor. Using geojson.io's drawing tools you can create points, lines, and polygons directly on a map.I particularly like geojson.io's table view, which makes it very easy to delete surplus features in your data. Geojson.io also has a number of options for exporting your data. As well as saving your finished data as geojson you can save spatial data in shapefile, topojosn, CSV or KML formats.
Vecor GeoJSON
Vector GeoJSON is another popular and useful online GeoJSON editor. Like geojson.io this online editor can be used to create or edit GeoJSON data directly from your browser.

useful article thank you. If I have a topojson map file of postcode boundaries or countries. How can I edit it to simply add two postcodes together or countries together then save as a new map?
both are useless if working with larger datasets
