HSV to CSV Converter

Parses hash-delimited text and re-serializes it using commas, the delimiter most tools and APIs expect. As with the CSV to HSV converter, "HSV" here is this site's own convenience name for a hash-delimited variant, not a formally standardized external format. A free online tool from Staaarter, right in your browser.

Overview

Introduction

If you (or another tool on this site) exported data using a hash `#` delimiter to avoid clashing with commas, tabs, semicolons, or pipes already present in the data, this tool converts it back into standard comma CSV.

Worth repeating up front: "HSV" is not an established external format, it's this site's own convenience name, so this converter specifically expects input using this site's own hash-delimiting convention.

What Is HSV to CSV Converter?

A delimiter-conversion tool that re-parses hash-separated values and re-serializes the same rows and columns using commas as the field separator instead.

It's the direct inverse of the CSV to HSV converter in this category.

How HSV to CSV Converter Works

The input is parsed character by character with the hash character as the delimiter, correctly handling quoted fields that contain hashes, commas, or embedded newlines.

The resulting grid of cells is re-serialized using commas, with any cell containing a comma, quote, or newline automatically wrapped in quotes.

When To Use HSV to CSV Converter

Use it to convert hash-delimited output from this site's CSV to HSV converter back into standard CSV for a spreadsheet, API, or script.

It's also useful for any other hash-delimited text following the same simple convention (one `#` between fields, RFC 4180-style quoting for embedded hashes).

Features

Advantages

  • Correctly handles RFC 4180-style quoting, so quoted fields containing hashes or commas convert without corruption.
  • Preserves row and column structure exactly, only the delimiter character changes.
  • Runs entirely client-side, so your data never leaves the browser.

Limitations

  • Since "HSV" isn't an external standard, there's no guarantee that hash-delimited text from another source follows the exact same quoting conventions this tool expects.
  • Doesn't attempt any other data cleanup or validation beyond changing the delimiter.

Examples

Converting hash-delimited values back to CSV

Input

id#name#active
1#Ada Lovelace#true
2#Alan Turing#false

Output

id,name,active
1,Ada Lovelace,true
2,Alan Turing,false

Each hash between fields becomes a comma; the row and column layout is otherwise unchanged.

Best Practices & Notes

Best Practices

  • Confirm the source of your hash-delimited text actually used one `#` as a plain field separator before converting, since this isn't a format with a single universally agreed-upon definition.
  • If your data legitimately contains hash characters inside values (hex colors, hashtags), confirm they were properly quoted in the source before converting.
  • Pair with CSV to HSV to verify a round trip reproduces your original data.

Developer Notes

This is a two-step pipeline over the shared CSV grid parser: parse with `#` as the delimiter, then re-stringify the same grid with `,` as the delimiter. The underlying mechanics are identical to every other delimiter converter in this category; only the delimiter character and the informal "HSV" label differ.

HSV to CSV Converter Use Cases

  • Converting hash-delimited exports from this site's CSV to HSV converter back into standard CSV
  • Normalizing a custom, project-specific hash-delimited export before handing it to a comma-CSV-only downstream system
  • Recovering standard CSV from data where commas, tabs, semicolons, and pipes were all already in use, hence the hash delimiter

Common Mistakes

  • Assuming any file someone calls "HSV" follows the exact same convention this tool expects; since it isn't a standardized format, conventions can vary between sources.
  • Forgetting that literal hash characters in the data (hex colors, hashtags) needed quoting in the source to round-trip correctly.

Tips

  • If a row has more fields than expected after conversion, check the source for unquoted literal hash characters inside what should have been a single value.
  • Use CSV to HSV afterward on the result to sanity-check the round trip.
