CSV to JSON converter, free and private
Describe a CSV once, map its columns, and download the rows as JSON. On a server the same mapping can push JSON or JSON Lines to an API.
CSV, TSV or Excel → JSON
Modules. Free in the browser. Transfer for delivery and Flow for schedules on a Server.
Edition. Free browser edition, Desktop or Server.
- Input files are CSV, TSV, Excel and custom-delimiter files. JSON is an output format, and what an HTTP source reads from an API.
- Free edition limits: CSV and TSV up to 10 MB, Excel up to 5 MB, 100,000 rows.
How it works.
Each step names the feature as it appears in the product.
- Step 1
File template
Describe the input: delimiter, header row, column names and types.
- Step 2
Field mapping
Rename columns to the property names your API or app expects, and clean values on the way.
- Step 3
Transform Data
Run the file and download the result as JSON. Errors are listed by row and column.
- Step 4
Validate File
Check a file against its template first, so bad rows are found before the JSON is made.
- Step 5
On a server
A Push results step can deliver JSON or JSON Lines to an HTTP endpoint, an SFTP server or cloud storage on a schedule.
Common questions.
Can DataBridge read a JSON file?
Not as a file template. HTTP sources read JSON from an API, using a records path to find the array of records.
Is JSON Lines supported?
Yes for delivery. A Push results step can write JSON, JSON Lines, CSV or TSV.
