Why this tool matters
Keep CSV exports, webhook payloads, and BI imports in sync without building throwaway scripts. The converter mirrors Laravel’s CSV helpers so large datasets behave the same way they will in production.
Spreadsheet exports
Paste CSVs from spreadsheets or SaaS dashboards and emit matching JSON arrays for docs or developer handoffs.
Webhook capture
Flatten JSON webhooks into CSV so analysts can pivot payloads without building ad-hoc scripts.
BI imports
Tune delimiters, quotes, and line endings so BI or CRM imports accept the converted output on the first try.
Quick start
Choose a direction, align the delimiter + header controls, and copy the normalized output.
- Launch the CSV ↔ JSON converter, review the hero summary, and pick CSV → JSON or JSON → CSV.
- Set the delimiter, quote style, header toggle, and line ending to match the source file or downstream consumer.
- Paste your payload into the Source panel, click Convert payload, then copy the normalized output or rerun with tweaks.
Supported inputs
- Accepts UTF-8 CSV up to PHP’s memory limits; commas, semicolons, tabs, and pipes are all supported.
- JSON input must decode into an array (list of records) or a single object—nested values stay intact via JSON encoding.
- Quote selector supports double or single quotes and the header toggle flips between reading the first row or emitting header labels.
Mode walkthroughs
Conversion modes
Follow these steps to mirror the UI controls for each direction.
CSV → JSON
- Choose CSV → JSON, set the delimiter, and enable “Treat first row as headers” if the CSV includes column labels.
- Paste or upload the CSV content into the Source payload editor and preview the stats panel for line counts.
- Submit the form to receive a prettified JSON array with each row mapped to headers; copy it into docs, seeds, or fixtures.
JSON → CSV
- Switch to JSON → CSV, keep the delimiter/quote options aligned with whoever will ingest the file.
- Paste an array of objects (or arrays) into the editor; use the Quick Samples if you need to sanity-check shapes.
- Run the converter and copy the CSV output—headers are auto-generated or omitted depending on the toggle.
Outputs & stats
Understand what the converter emits plus the sanity checks baked into the sidebar.
Converted output mirrors the input editor font so row-to-row diffs remain readable before you commit changes.
Stats card surfaces row count, column count, and header detection so you can validate shape without scrolling.
Copy indicator confirms when the CSV or JSON output hits your clipboard—perfect when hopping between spreadsheets and IDEs.
Feature deep dives
Every control matches a real-world workflow—here’s how to leverage them.
Delimiter + quote controls
Swap between comma, semicolon, tab, or pipe plus single/double quotes to match locale-specific exports.
Header detection
Treat the first row as headers or auto-generate labels so JSON arrays always line up with CSV columns.
Line ending presets
Emit Unix (LF) or Windows (CRLF) endings to avoid merge churn and appease finicky importers.
Field notes & pro tips
Keep these reminders handy when rotating on call or prepping data handoffs.
- Auto-detect delimiter issues by pasting the CSV and watching whether the column count spikes unexpectedly.
- Use the JSON → CSV mode to prep lightweight incident summaries for BI teams without emailing raw JSON blobs.
- Link to this guide from your README so reviewers know which delimiter + line ending presets to expect.
- Pair with the YAML ↔ JSON converter to move between CSV, JSON, and YAML during migration planning.
