Spreadsheet exports
Turn CSV files into JSON arrays for docs, fixtures, or handoffs.
Documentation
CSV ↔ JSON converter documentation
Move between CSV exports and JSON arrays with delimiter, quote, header, and line-ending controls.
Overview
Use it when the format needs to change, not the meaning
Use the converter when rows need to move cleanly between spreadsheet-style files and JSON records.
Webhook flattening
Convert nested JSON into CSV when a tabular consumer needs it.
Import prep
Tune headers and line endings before you send the file to another system.
Supported inputs
Bring clean source text and keep the direction straight
- Accepts UTF-8 CSV with commas, semicolons, tabs, or pipes.
- JSON input can be an array of records, a single object, or a scalar value.
- Header and quote controls should match the format expected by the next system.
Walk through it
Follow the same sequence you see in the tool
Workflow
CSV to JSON
Use this path when a tabular file needs to become structured JSON.
- Choose CSV to JSON and set the delimiter.
- Turn on the header option if the first row contains labels.
- Paste the CSV and copy the JSON output when it is ready.
Workflow
JSON to CSV
Use this path when structured data needs a row and column shape.
- Switch to JSON to CSV and keep the delimiter settings aligned with the target system.
- Paste the JSON payload and check that the record shape is consistent.
- Run the conversion and copy the CSV result for the next step.
What you get
Check the result before you copy it into the next step
JSON records
The converted array is ready to paste into fixtures, docs, or scripts.
CSV rows
The converted table is ready for spreadsheets, imports, or row-based tools.
Row and column counts
Counts help you check that the structure still matches the source.
Avoid these mistakes
Small input problems create the biggest conversion errors
Wrong delimiter
Match the delimiter to the source file before you trust the output.
Headers skipped by accident
Confirm whether the first row is data or a column label before converting.
Nested values flattened without review
Check the JSON result when a cell contains arrays or objects.
Glossary
Decode the terms before you act on them
This section translates the most technical labels on the page into plain language so you can interpret the output without opening another tab.
Delimiter
A delimiter is the character that separates CSV fields, such as a comma, semicolon, tab, or pipe.
Header row
The header row is the first CSV row when it contains column names instead of real data values.
Record
A record is one logical item in the converted data, whether it is represented as a CSV row or a JSON object.
Flattening
Flattening turns nested arrays or objects into a simpler tabular shape so they can fit into CSV columns.
