SnapOtter d24e244af4 docs: organize tool pages by modality under /tools/<modality>/
Move all 157 tool pages into image/video/audio/pdf/data subfolders so URLs read /tools/<modality>/<id> (e.g. /tools/image/crop). Nest the image sub-categories under an Image group in the sidebar so the nav reads by modality. Add public/_redirects (301, clean + .html forms) mapping every old flat /tools/<id> URL to its new path so inbound links keep working. Rewrite all internal /tools links. Verified with a clean docs build (no dead links).

Split a CSV into smaller files by row count.

Split CSV

Split a large CSV or TSV file into smaller files by row count. Returns a ZIP archive containing the parts.

API Endpoint

POST /api/v1/tools/data/split-csv

Accepts multipart form data with a CSV file and a JSON settings field.

Parameters

Parameter Type Required Default Description
rowsPerFile integer No 1000 Number of data rows per output file (1--1,000,000)
keepHeader boolean No true Repeat the header row in each output file

Example Request

curl -X POST http://localhost:1349/api/v1/tools/data/split-csv \
  -H "Authorization: Bearer si_your-api-key" \
  -F "file=@large-dataset.csv" \
  -F 'settings={"rowsPerFile": 500, "keepHeader": true}'

Example Response

{
  "jobId": "a1b2c3d4-e5f6-7890-abcd-ef1234567890",
  "downloadUrl": "/api/v1/download/a1b2c3d4-e5f6-7890-abcd-ef1234567890/large-dataset-split.zip",
  "originalSize": 1048576,
  "processedSize": 1050000
}

Notes

  • Output is always a ZIP archive containing the split CSV parts, named sequentially (e.g. part-1.csv, part-2.csv).
  • When keepHeader is true, each part includes the original header row so each file can be used independently.
  • Both CSV and TSV files are accepted as input.
  • The row count refers to data rows only; the header row is not counted.
